'Acquainted' in the Bible

And this is how we know [daily, by experience] that we have come to know Him [to understand Him and be more deeply acquainted with Him]: if we habitually keep [focused on His precepts and obey] His commandments (teachings).

Whoever says, “I have come to know Him,” but does not habitually keep [focused on His precepts and obey] His commandments (teachings), is a liar, and the truth [of the divine word] is not in him.

The one who does not love has not become acquainted with God [does not and never did know Him], for God is love. [He is the originator of love, and it is an enduring attribute of His nature.]
