1 Corinthians 6:18

18 Avoid immorality. Any other sin a man commits does not affect his body; but the man who is guilty of sexual immorality sins against his own body.

1 Corinthians 6:18 Meaning and Commentary

1 Corinthians 6:18

Flee fornication
As that which is hurtful, scandalous, and unbecoming Christians; avoid it, and all the occasions of it, that may lead unto it, and be incentives of it:

every sin that a man doth is without the body
not but that other sins are committed by the body, and by the members of it as instruments; they are generally committed by the abuse of other things that are without, and do not belong to the body; and so do not bring that hurt unto and reproach upon the body, as fornication does:

but he that committeth fornication, sinneth against his own body;
not meaning his wife, which is as his own body; but his proper natural body, which is not only the instrument by which this sin is committed, but the object against which it is committed; and which is defiled and dishonoured by it; and sometimes its strength and health are impaired, and it is filled with nauseous diseases hereby.

1 Corinthians 6:18 In-Context

16 Or perhaps you don't know that the man who joins his body to a prostitute becomes physically one with her? The scripture says quite plainly, "The two will become one body."

17 But he who joins himself to the Lord becomes spiritually one with him.

18 Avoid immorality. Any other sin a man commits does not affect his body; but the man who is guilty of sexual immorality sins against his own body.

19 Don't you know that your body is the temple of the Holy Spirit, who lives in you and who was given to you by God? You do not belong to yourselves but to God;

20 he bought you for a price. So use your bodies for God's glory.
