The Twelve Doors
No one leaves home expecting to be robbed.
Yet before going to bed, most of us instinctively check the doors. We lock the deadbolt, lower the garage door, and make sure the windows are secure. We know that thieves look for easy opportunities.
The Apostle Paul gives the church similar warnings:
“Be sober-minded; be watchful. Your adversary the devil prowls around like a roaring lion, seeking someone to devour.” (1 Peter 5:8, ESV)
"Be angry and do not sin; do not let the sun go down on your anger, and give no opportunity to the devil." (Ephesians 4:26–27, ESV)
The word translated opportunity literally refers to giving someone a place, a foothold, or room to operate. In other words, Paul is saying, "Don't leave the door open."
That is precisely how Satan most often works in healthy churches.
He rarely begins by introducing false doctrine or convincing believers to abandon Christ altogether. Instead, he quietly looks for an unlocked door—a careless word, a wounded heart, an unchecked attitude, or an unresolved conflict. Through these seemingly small openings, division gradually enters the body of Christ.
Jesus prayed that His followers would be one (John 17:20–23), and Paul urged believers to be "eager to maintain the unity of the Spirit in the bond of peace" (Ephesians 4:3). Unity is not something we create; it is something we diligently protect.
So what doors should we be careful never to leave open?
Door #1: Gossip
The Open Door
Gossip often masquerades as concern, curiosity, or even a prayer request. Yet Scripture warns,
“So also the tongue is a small member, yet it boasts of great things.How great a forest is set ablaze by such a small fire! And the tongue is a fire, a world of unrighteousness. The tongue is set among our members, staining the whole body,setting on fire the entire course of life, and set on fire by hell.” (James 3:5–6, ESV)
Have only good things to say
Words have enormous power. They can strengthen trust or quietly destroy it.
Close the Door With... Truth Spoken in Love
“Let no corrupting talk come out of your mouths, but only such as is good for building up, as fits the occasion, that it may give grace to those who hear.” (Ephesians 4:29, ESV)
“Let your speech always be gracious, seasoned with salt, so that you may know how you ought to answer each person.” (Colossians 4:6, ESV)
“Gracious words are like a honeycomb, sweetness to the soul and health to the body.” (Proverbs 16:24, ESV)
Door #2: Complaining
The Open Door
Complaining spreads discouragement faster than almost anything else.
Israel's constant grumbling in the wilderness revealed hearts that doubted God's goodness, and Paul warns believers:
"Do all things without grumbling or disputing." (Philippians 2:14)
“Show hospitality to one another without grumbling.” (1 Peter 4:9, ESV)
“Do not grumble against one another, brothers, so that you may not be judged; behold, the Judge is standing at the door.” (James 5:9, ESV)
Negativity is contagious.
Close the Door With... Gratitude
A thankful heart leaves little room for resentment.
"Give thanks in all circumstances..." (1 Thessalonians 5:18)
“And let the peace of Christ rule in your hearts, to which indeed you were called in one body. And be thankful.” (Colossians 3:15, ESV)
Door #3: Judgmentalism
The Open Door
Judgmentalism assumes the role that belongs to God alone. Jesus warned,
"Judge not, that you be not judged." (Matthew 7:1)
There is a difference between biblical discernment and condemning another person's heart.
Close the Door With... Humility
Approach others remembering your own need for grace.
"With all humility and gentleness... bearing with one another in love." (Ephesians 4:2)
“…Clothe yourselves, all of you, with humility toward one another, for “God opposes the proud but gives grace to the humble.” Humble yourselves, therefore, under the mighty hand of God so that at the proper time he may exalt you,” (1 Peter 5:5b–6, ESV)
“Do nothing from selfish ambition or conceit, but in humility count others more significant than yourselves. Let each of you look not only to his own interests, but also to the interests of others.” (Philippians 2:3–4, ESV)
Door #4: Pride
The Open Door
Pride quietly whispers,
"I deserve more."
"My opinion matters most." "I've earned the right."
Nothing fractures unity faster than self-centeredness.
“When pride comes, then comes disgrace, but with the humble is wisdom.” (Proverbs 11:2, ESV)
“But he gives more grace. Therefore it says, “God opposes the proud but gives grace to the humble.”” (James 4:6, ESV)
Close the Door With... Servanthood
Paul points us to Christ, who humbled Himself and took the form of a servant (Philippians 2:5–8).
“…whoever would be great among you must be your servant, and whoever would be first among you must be the slave of all. For even the Son of Man came not to be served but to serve, and to give his life as a ransom for many.”” (Mark 10:43–45, ESV)
“For you were called to freedom, brothers. Only do not use your freedom as an opportunity for the flesh, but through love serve one another.” (Galatians 5:13, ESV)
Door #5: Unforgiveness
The Open Door
Every church experiences hurt.
The question is whether those wounds become bitterness. Paul directly connects forgiveness with resisting Satan:
"...so that we would not be outwitted by Satan. For we are not ignorant of his schemes." (2 Corinthians 2:10–11)
“For if you forgive others their trespasses, your heavenly Father will also forgive you, but if you do not forgive others their trespasses, neither will your Father forgive your trespasses.” (Matthew 6:14–15, ESV)
Close the Door With... Grace
Forgive because Christ first forgave you.
“Be kind to one another, tenderhearted, forgiving one another, as God in Christ forgave you.” (Ephesians 4:32, ESV)
“bearing with one another and, if one has a complaint against another, forgiving each other; as the Lord has forgiven you, so you also must forgive.” (Colossians 3:13, ESV)
Door #6: Suspicion
The Open Door
One of Satan's quietest whispers is:
"You know what they really meant."
Most church conflicts begin not with facts but with emotional assumptions.
“he is puffed up with conceit and understands nothing. He has an unhealthy craving for controversy and for quarrels about words, which produce envy, dissension, slander, evil suspicions,” (1 Timothy 6:4, ESV)
Close the Door With... Honest Loving Conversation
Love gives the benefit of the doubt.
“Love bears all things, believes all things, hopes all things, endures all things.” (1 Corinthians 13:7, ESV)
“Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths.” (Proverbs 3:5–6, ESV)
“but test everything; hold fast what is good.” (1 Thessalonians 5:21, ESV)
When in doubt, gently and respectfully ask instead of assuming.
Door #7: Fear
The Open Door
Fear often disguises itself as wisdom. Fear of change.
Fear of losing traditions. Fear of losing influence.
Fear causes us to cling to what is familiar instead of trusting God.
“There is no fear in love, but perfect love casts out fear. For fear has to do with punishment, and whoever fears has not been perfected in love.” (1 John 4:18, ESV)
Close the Door With... Faith
"For God gave us a spirit not of fear but of power and love and self-control." (2 Timothy 1:7)
Door #8: Comparison
The Open Door
Comparison steals joy.
Instead of celebrating another believer's gifts, we can become threatened by them. Paul says,
"...they are without understanding." (2 Corinthians 10:12)
“A tranquil heart gives life to the flesh, but envy makes the bones rot.” (Proverbs 14:30, ESV)
“But if you have bitter jealousy and selfish ambition in your hearts, do not boast and be false to the truth. This is not the wisdom that comes down from above, but is earthly, unspiritual, demonic. For where jealousy and selfish ambition exist, there will be disorder and every vile practice.” (James 3:14–16, ESV)
Close the Door With... Contentment
“… I have learned, in whatever situation I am, to be content. I know how to be brought low, and I know how to abound. In any and every circumstance, I have learned the secret of facing plenty and hunger, abundance and need. I can do all things through him who strengthens me.” (Philippians 4:11–13, ESV)
Door #9: Isolation
The Open Door
Predators separate prey from the herd. Satan loves isolated believers.
Discouragement often begins with withdrawal.
“And let us consider how to stir up one another to love and good works, not neglecting to meet together, as is the habit of some, but encouraging one another, and all the more as you see the Day drawing near.” (Hebrews 10:24–25, ESV)
“Whoever isolates himself seeks his own desire; he breaks out against all sound judgment.” (Proverbs 18:1, ESV)
Close the Door With... Fellowship
“Two are better than one, because they have a good reward for their toil. For if they fall, one will lift up his fellow. But woe to him who is alone when he falls and has not another to lift him up! Again, if two lie together, they keep warm, but how can one keep warm alone? And though a man might prevail against one who is alone, two will withstand him—a threefold cord is not quickly broken.” (Ecclesiastes 4:9–12, ESV)
Christianity has never been intended as a solo journey.
Door #10: Consumerism
The Open Door
Modern culture teaches us to ask,
"What do I get out of church?"
Scripture asks,
"How can I serve Christ and His people?"
Consumers leave. Families persevere.
“For the time is coming when people will not endure sound teaching, but having itching ears they will accumulate for themselves teachers to suit their own passions, and will turn away from listening to the truth and wander off into myths.” (2 Timothy 4:3–4, ESV)
“But understand this, that in the last days there will come times of difficulty. For people will be lovers of self, lovers of money, proud, arrogant, abusive, disobedient to their parents, ungrateful, unholy, heartless, unappeasable, slanderous, without self-control, brutal, not loving good, treacherous, reckless, swollen with conceit, lovers of pleasure rather than lovers of God, having the appearance of godliness, but denying its power. Avoid such people.” (2 Timothy 3:1–5, ESV)
Close the Door With... Service
Jesus Himself came "not to be served but to serve" (Mark 10:45).
“But seek first the kingdom of God and his righteousness, and all these things will be added to you.” (Matthew 6:33, ESV)
““Do not lay up for yourselves treasures on earth, where moth and rust destroy and where thieves break in and steal, but lay up for yourselves treasures in heaven, where neither moth nor rust destroys and where thieves do not break in and steal. For where your treasure is, there your heart will be also.” (Matthew 6:19–21, ESV)
Door #11: Distraction
The Open Door
Sometimes Satan doesn't need us to become sinful. He simply needs us to become busy.
Busy enough to neglect prayer. Busy enough to neglect worship.
Busy enough to neglect Christ Himself.
“Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. For all that is in the world—the desires of the flesh and the desires of the eyes and pride of life—is not from the Father but is from the world. And the world is passing away along with its desires, but whoever does the will of God abides forever.” (1 John 2:15–17, ESV)
Close the Door With... Abiding
Jesus gently reminded Martha,
"One thing is necessary." (Luke 10:42) Everything else flows from that one thing.
“Set your minds on things that are above, not on things that are on earth.” (Colossians 3:2, ESV)
Door #12: Preferences Elevated to Principles
The Open Door
Perhaps no door has divided more churches than treating personal preferences as though they were biblical commands.
Methods become doctrines. Traditions become absolutes. Opinions become tests of fellowship.
Suddenly wisdom issues become gospel issues.
“Trust in the Lord with all your heart, and do not lean on your own understanding. In all your ways acknowledge him, and he will make straight your paths. Be not wise in your own eyes; fear the Lord, and turn away from evil.” (Proverbs 3:5–7, ESV)
“A fool takes no pleasure in understanding, but only in expressing his opinion.”
(Proverbs 18:2, ESV)
Close the Door With... Biblical Discernment
Hold tightly to God's Word.
“Do not be conformed to this world, but be transformed by the renewal of your mind, that by testing you may discern what is the will of God, what is good and acceptable and perfect.” (Romans 12:2, ESV)
“but test everything; hold fast what is good.” (1 Thessalonians 5:21, ESV)
“Now these Jews were more noble than those in Thessalonica; they received the word with all eagerness, examining the Scriptures daily to see if these things were so.” (Acts 17:11, ESV)
Hold graciously to personal preferences.
Close Every Door
Notice something remarkable about these twelve doors. None of them appear especially dangerous at first.
A little gossip. A small offense.
A wounded ego. An unchecked fear. A private grudge.
A preference defended just a little too strongly.
Left unattended, however, each becomes an invitation for Satan to gain a foothold in Christ's church.
The encouraging news is that God has provided a key for every door the enemy hopes to open. Truth overcomes gossip. Gratitude silences complaining. Humility defeats pride. Grace heals unforgiveness. Honest conversation dispels suspicion. Faith overcomes fear. Contentment defeats comparison. Fellowship counters isolation. Service overcomes consumerism. Abiding in Christ defeats distraction. Biblical discernment keeps preferences in their proper place.
Healthy churches are not churches without problems. They are churches filled with believers who refuse to leave doors open for the enemy.
May we therefore "walk in a manner worthy of the calling to which you have been called... eager to maintain the unity of the Spirit in the bond of peace" (Ephesians 4:1–3). As we do, we not only protect the unity of Christ's church—we also deny the enemy the foothold he so desperately seeks.
