“My Father has given all things to me. The Father is the only one who knows the Son. And the only ones who know the Father are the Son and those to whom the Son chooses to make him known.
“My Father has given all things to me. The Father is the only one who knows who the Son is. And the only ones who know the Father are the Son and those to whom the Son chooses to make the Father known.”
Who is the liar? It is anyone who says that Jesus is not the Christ. The person who says this is the great enemy of Christ. They say no to the Father and the Son.
We also know that the Son of God has come. He has given us understanding. So we can know the God who is true. And we belong to the true God by belonging to his Son, Jesus Christ. He is the true God and eternal life.
