What does 1 Corinthians 8:3 mean?

In their earlier letter to Paul (1 Corinthians 7:1), the Corinthians seem to have raised the issue of eating food offered to idols. Perhaps they are challenging his former teaching to them about it by saying that "all of us possess knowledge." Paul has pointed out two problems with knowledge. First, knowledge alone creates only pride, while love builds people up (1 Corinthians 8:1). Second, just because someone believes they know does not mean they actually know (1 Corinthians 8:2).

Paul adds again that love is what truly matters, especially when that love is directed toward God. Here again, he uses the Greek root word agapao, referring to a selfless and sacrificial love.

Even better than having knowledge of God is to be known by Him. Those who love Him are known by Him. Being known by God, in turn, means that we belong to Him. Those who belong to God, Paul will eventually show, must completely separate themselves from demons, the real force behind the worship of idols and gods (1 Corinthians 10:20–21).
