“But if any man loue God, the same is knowen of him.”
1611 King James Version (KJV)
8:3 He is known - That is, approved, by him. #Psalm 1:6|.
1Co 8:3 If any man love God. Not knowledge, but love "buildeth up" (1Co 8:1). Love, too, is a source of true knowledge. It is he who loves God who knows him. The same, grammatically, refers to God. The sentence then says, "If any man love God, the same is known by him", i.e., by that man. Love is the means of obtaining the true knowledge, the highest knowledge.
