“See what an incredible quality of love the Father has given us that we should be permitted to be named, called, and counted the children of God! And so we are! The reason that the world does not know us is that it does not know or acknowledge Him.” 1 John 3:1
To understand this verse we first have to understand the meaning of the word know. To know someone is not just to be acquainted with them. The way this word is used here means to understand. So if someone doesn’t seem to understand why you feel so strongly about your faith in God and Christ, it’s because they don’t know or understand and know God.
This verse further tells us about the incredible quality of love that the Father gives us His children. NO ONE will ever love you as much as God does, and He will never disappoint you or hurt you in any way.
That is an incredible love.
