18 “Flee sexual immorality. Every sin that a man does is outside the body, but he who commits sexual immorality sins against his own body.”
Flee sexual immorality.
When it comes to temptation regarding a sex sin – flee it. The Greek indicates immediate and decisive disassociation from sexual sin. The Greek word is the word from which we get the English word “fugitive.” “Become a fugitive from sexual sins.” There is internal injury with sexual sins, so it is not something we debate or discourse about.
1 Thessalonians 4:3 For this is the will of God, your sanctification: that you should abstain from sexual immorality;
Every sin that a man does is outside the body,
Other sins such as thievery and lying do not affect the body, but the body itself is the instrument of sin in immorality.
but he who commits sexual immorality sins against his own body.
Fornication violates the body and the body is the dwelling place of the Holy Spirit. Immorality like no other sin is internal and desecrates the temple of the Lord.
We do not debate sexual sins but deal with them decisively.
There is a consistent counsel from the Word of God when it comes to sex sins – “flee.” Don’t think about it. Don’t go for counseling about it. Don’t debate it. Don’t even fight it. Flee it. That is what Joseph did when he fled from Potiphar’s wife (Ge 39).
There is a constructive side to dealing with the sin of immorality – “pursue.” After a believer flees sexual sin, he is to aggressively pursue what he puts into his mind.
2 Timothy 2:22 Flee also youthful lusts; but pursue righteousness, faith, love, peace with those who call on the Lord out of a pure heart.
