1 Corinthians 7:9 (ESV)

9 But if they cannot exercise self-control, they should marry. For it is better to marry than to burn with passion.

Paul has already pointed out that there are exceptions to the general principle that it is good not to marry. It is better, namely, to marry than to be tempted to sexual immorality (1 Corinthians 7:2). He repeats this caution, this time applying it specifically to the unmarried.

The phrase to burn with passion is a figurative translation, where the literal translation would simply be to burn. Elsewhere, Paul also uses the word burn to refer to a strong emotion (2 Corinthians 11:29).

The point is that it is better to marry if one does not have the self-control to subdue one’s sexual desires. For similar counsel, see 1 Corinthians 7:5 and 1 Timothy 5:11–15.
