“All things have been handed over to Me by My Father. And no one knows who the Son is but the Father, and who the Father is but the Son and he to whom the Son desires to reveal Him.”
Consider how much love the Father has given to us, that we should be called children of God. Therefore the world does not know us, because it did not know Him.
And we know that the Son of God has come and has given us understanding, so that we may know Him who is true, and we are in Him who is true —His Son Jesus Christ. He is the true God and eternal life.
