1 Corinthians 6:12
"Everything is permissible for me [to do];" but not everything is profitable. [Note: The words in quote marks in this and the following verse are thought to have been commonly held views of that day, to which Paul gives an inspired reply]. "Everything is permissible for me [to do];" but I will not be ruled by anything.
1 Corinthians 6:18
Stay away from [any involvement in] sexual immorality. Every sin a person commits is outside [the realm] of his body; but the one who commits sexual immorality sins against his own body. [Note: Possibly this means that sex, because it requires the deepest and most complete commitment of human involvement, becomes a unique sin when its true purpose and expression are violated].
Ephesians 4:17-19
So, I tell you this, and insist [on it] by [the authority of] the Lord: Do not continue to live with worthless thoughts as [unconverted] Gentiles do.
Ephesians 5:3-11
But you should not even talk about sexual immorality, or any type of [moral] impurity, or greed. [Note: Possibly "greed" here means "desire for more" of such things]. Such talk is not suitable for saints [i.e., God's holy people].
1 Thessalonians 4:3-5
For it is God's will that you should be dedicated to Him, [that is], you should avoid sexual immorality.
2 Timothy 2:22
But run from the evil desires of youth and pursue [the practice of] right living, faith, love and peace, along with those people who call on the Lord [i.e., in prayer] from a pure heart.
Hebrews 13:4
Marriage should be considered honorable among all people and its sexual responsibilities should be faithfully kept. For God will judge [and condemn] those people who are sexually immoral and who are sexually unfaithful to their mates.
1 Peter 2:11
My dearly loved ones, I urge you, as a people who are foreigners and strangers [in this world], do not give in to sinful desires, which wage war against the soul.
