What does John 3:35 mean?

Jesus frequently claims to have the Father's knowledge (John 12:49), power (John 5:36), and authority (Matthew 28:18). In this way, He claims to be equal to God. The gospel of John clearly says that Jesus is not merely similar to God—He is God (John 1:1; John 1:14). This is another useful demonstration of the Trinity, which is the idea that God is three persons in one being: the Father, the Son, and the Holy Spirit. Jesus' message is that of God, which is why a person cannot reject Christ without rejecting God (1 John 5:10). If a person will not accept Jesus, then they cannot be saved (John 3:18)—Jesus is the one and only way to the Father (John 14:6).

The fact that God the Father loves God the Son makes His willingness to send Him to us that much more amazing (1 John 4:9–10). Jesus' sacrifice on the cross was not just a gift, it was a very costly one.
