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 Do you not know that he who joins himself to a prostitute becomes one body with her? For, as it is written, "The two shall become one flesh."

17 But he who is united to the Lord becomes one spirit with him.

18 Shun immorality. Every other sin which a man commits is outside the body; but the immoral man sins against his own body.

19 Do you not know that your body is a temple of the Holy Spirit within you, which you have from God? You are not your own;

20 you were bought with a price. So glorify God in your body.
