“For the Father loves the Son and shows him everything he is doing. In fact, the Father will show him how to do even greater works than healing this man. Then you will truly be astonished.” John 5:20
Jesus completes the revelation of the Father and it is grounded in the Father’s own love for the Son and the fact that the Father has not held anything back from the Son. For the Father loves the Son and shows him all he does. The Father’s love is the heart of everything. “For this is how God loved the world: He gave his one and only Son, so that everyone who believes in him will not perish but have eternal life.” (John 3:16) God’s love for the world leads him to send the Son so we may be able to share through the Spirit in the Father’s love for the Son. This eternal relationship is the source of Jesus’ activity, for it leads the Father to show the Son all he does. We see in this verse the Father takes the initiative; he is in control, and he is the source of all. This passage also emphasizes that the Father has held back nothing of his activities from the Son.
Jesus’ healing on the Sabbath and his other deeds have amazed people, but he promises the Father will show the Son even greater things. Jesus’ desire for his opponents to be amazed is not due to any interest he might have in their acclaim–he does not care for human praise. Rather, Jesus works miracles that, like the miracles of Moses, will make people sit up and take notice and recognize that God has sent him. But on a deeper level, God seeks an amazement that comes from recognizing the Father in the Son, for the miracles actually reveal the identity of Jesus and the character of the Father. As we learn more of God, we continue to be amazed. If we are not amazed by Jesus, then we, like the Jewish leaders, have not yet really seen him.
