Knowledge puffs up, love builds up-1 Corinthians 8:1, NIV
But the man who loves God is known by God vs 3.
1 Corinthians 8:1-3
[1]Now, concerning what you wrote about food offered to idols.It is true, of course, that “all of us have knowledge”, as they say. Such knowledge, however, puffs a person up with pride; but love builds up.
[2]Those who think they know something really don’t know as they ought to know.
[3]But the person who loves God is known by him.
