Does the identity of God have to be “a very profound mystery”? It did not seem so to Jesus. In his prayer to his Father, Jesus made a clear distinction between him and his Father when he said: “This means everlasting life, their taking in knowledge of you, the only true God, and of the one whom you sent forth, Jesus Christ.” (John 17:3) If we believe Jesus and understand the plain teaching of the Bible, we will respect him as the divine Son of God that he is.
In addition, Matthew 24:36 However, no one knows the day or hour when these things will happen, not even the angels in heaven or the Son himself. Only the Father knows.
