It is God’s will that you should be sanctified: that you should avoid sexual immorality; that each of you should learn to control his own body in a way that is holy and honorable, not in passionate lust like the heathen, who do not know God; and that in this matter no one should wrong his brother or take advantage of him.

The Lord will punish men for all such sins, as we have already told you and warned you. For God did  not call us to be impure, but to live a holy life. Therefore, he who rejects this instruction does not reject man but God, who gives you his Holy Spirit. I Thessalonians 4:3-8

Flee from sexual immorality. All other sins a man commits are outside his body, but he who sins sexually sins against his own body. I Corinthians 6:18

But among you there must not be even a hint of sexual immorality, or of any kind of impurity, or of greed, because these are improper for God's holy people. Ephesians 5:3

Put to death, therefore, whatever belongs to your earthly nature: sexual immorality, impurity, lust, evil desires... Colossians 3:5

An interesting thing about sin - any sin - is that we do know it is sin; no one has to point it out to us. If any of us struggle with any impurities let us bring it to the Lord's presence this morning,confess and be washed by His blood all over again.
