Matthew 11:25-27 is firm evidence for the distinction of persons between the Father and the Son. Listen in, “I thank you, Father, Lord of heaven and earth, that you have hidden these things from the wise and understanding and revealed them to little children; yes, Father, for such was your gracious will. All things have been handed over to me by my Father, and no one knows the son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him.” When you add 1 Corinthians 15:27-28 the argument for the distinction of persons is quite strong.
Jesus’ point in Matthew 11:25-27 is that his Father, the person to whom he is actually praying, is hidden. The mysterious Father chooses to reveal himself to the humble and the simple. The way the Father reveals himself is through his Son. This Son is a person who knows the Father, also a person, and reveals the Father to those humble people. Jesus is not revealing himself as the Father. Jesus, who is the image of the invisible God, is making the invisible God known.
Additionally, there is an interchange between the persons of God. The Father gives all things to the Son so that he can redeem and rule over them all. And there is no paper tiger at work here. God is not three persons on paper but one person in reality. God is one. God is three persons in perfect mysterious unity. There is one God who exists in three persons working together for the redemption of all things and the revelation of the Father.
