What opens doors to lust?

Fall Sin

TL;DR:

Lust rarely breaks down the door—it slips through the cracks we leave open by entertaining tempting images, thoughts, and desires. Close those cracks by fleeing temptation, guarding your heart, and fixing your eyes on Christ.

what does the bible say?

The Bible teaches us to guard against lust in deed and thought. Dwelling on improper desires, not keeping thoughts pure, and not fleeing from the source of temptation can open the door to lust. The Bible shows that sin is not just about deeds but about our heart. The last of the Ten Commandments is about coveting, the sin of desiring something or someone that belongs to another (Exodus 20:17). Jesus also identified lust of the heart as sinful (Matthew 5:28). Proverbs speaks of guarding the heart (Proverbs 4:23a). James warns about cultivating sinful desires (James 4:7), and Paul advises Timothy to flee from them (2 Timothy 2:22; cf. 1 John 2:15-16). The Bible also provides examples of the devastating consequences of not turning away from lust, such as David's multiple sins because of his lust for Bathsheba (2 Samuel 11:3-4). We can resist Satan, the one who often tempts us with lust (James 4:7). Keeping our thought life pure and focused on Christ is the most effective way to close the door to lust (Philippians 4:8; Hebrews 12:2).

from the old testament

Lust often comes first through the eyes, so we should remove ourselves from that temptation—turn away from it—when we encounter it. David committed adultery (and eventually, murder) because, rather than turning away when he saw Bathsheba, he "sent and inquired about" her and then "took her" (2 Samuel 11:3-4).
Desires, including lust, are cultivated within. Proverbs exhorts us to "Keep your heart with all vigilance" (Proverbs 4:23a; cf. Exodus 20:17). We do this by avoiding encounters that encourage lust, whether in movies, books, or people.

from the new testament

Allowing personal desire to grow can open the door to lust: "But each person is tempted when he is lured and enticed by his own desire. Then desire, when it has conceived, gives birth to sin, and sin, when it is fully grown, brings forth death" (James 1:14).
Jesus explained that lust is a sin of the heart, not just of deed (Matthew 5:28). An impure thought life can open the door to lust. Paul exhorts believers to keep their thought life focused on what is pure (Philippians 4:8).
Love for "the things in the world" (1 John 2:15) can open the door to lust. John writes, "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" (1 John 2:16).
Practicing daily spiritual disciplines—prayer and Bible reading—help keep our focus on God. Paul encouraged Timothy to "flee youthful passions and pursue righteousness" (2 Timothy 2:22; emphasis added; cf. Hebrews 12:2).
Satan, the original tempter, can open the door to lust by putting temptations in believers' paths, but God's word tells us, "Resist the devil, and he will flee from you" (James 4:7).

implications for today

In horror movies, the vampire can't enter your house unless you invite it in. Many a moviegoer has screamed "No, no!" as the future victim invites the vampire in. The results are predictable.

That's fiction. But in real life, we metaphorically open the door to all sorts of dangerous things, including lust. And the danger threatens our spiritual life and relationship with God. According to a poll published by Barna in 2024, more than half of Christians use pornography with some frequency. It could start with watching a movie that society accepts as normal, but that contains racy scenes. Or maybe it's a book that has unwholesome material (today's "romance novels" are often just "soft" pornography). Those doors lead to lust.

Rather than filling our minds with that material, we should read God's word, participate in a Bible study, and listen to Christian podcasts. Don't allow the "vampire" to cross the threshold.
