What does Matthew 11:27 mean?
Christ paused His talk to the crowds with a prayer of thanks to His Father. He thanked God for hiding the truth of "these things" from those who are wise and understanding and revealing the truth instead to little children (Matthew 11:25–26). His meaning is that those who arrogantly think they are wise—and reject God as a result—are blinded to the truth. Those the world dismissed as simpletons and children are willing to accept what is real.Now Jesus adds another comment about the information God chooses to reveal. He claims to know what God the Father knows, and to know God the Father Himself. God knows everything, and God the Father has given to Jesus "all things." Nobody truly knows the Son, Jesus, except for God the Father. In the same way, nobody truly knows the Father except for Jesus, the Son, and those to whom Jesus chooses to reveal the Father.
This describes a profoundly interconnected relationship between Jesus Christ and God the Father. They know each other completely. The Father has revealed all truth, all things, to Jesus, the Son. They are both united as God together in the Trinity, along with the Holy Spirit. Yet, they are somehow distinct from each other. This is a great mystery, but it is also a great declaration. Jesus is not hiding who He truly is from those who are listening. He is fully claiming to be the Son of God.
Jesus is also declaring that He has the power and authority to reveal the Father to people on earth, according to His own choice. In fact, Jesus is the only way in the universe for human being to come to know God the Father by beginning a relationship with Him (John 14:6).
