Peter demonstrated the validity of Christ’s prophecy that he was the solid rock. Speaking on behalf of the rest he replied, "Lord, to whom shall we go? You alone are the source of eternal life." He may not have fully grasped Jesus’ intentions, but felt deep down that the man Jesus of Nazareth was the Lord from heaven, from whom proceed creative words with reviving power, not those of a mere man. Peter believed that the Lord was present. He shared in the distribution of the bread. Jesus’ hand held him up when he was about to sink. Peter’s heart was attached to Jesus, he loved his Lord more than anything else, and would not leave him. Peter chose Jesus, because Jesus had first chosen him.
The leader of the apostles concluded his testimony with these words, "We have believed and know". Notice, he did not say, "We knew and then believed." For it is faith that opens the hearts’ vision. It is our faith that lights up our minds. Thus Peter and his fellow disciples yielded to the attraction of God’s Spirit, who had led him to faith in Jesus illumining them to know the truth. They grew in their realization of his hidden glory. All true knowledge from Jesus is directly a gracious gift of God.
What was the nature of the disciples’ faith in Jesus? What was the content of this faith? They were attached with the divine Messiah, in whom the fullness of the Spirit dwelt. He united in his Person all the functions of priesthood, kingship and prophecy. Kings, high priests and prophets in the Old Testament were anointed by the Holy Spirit. In Christ are combined all the energies and blessings of heaven. He is the divine King omnipotent; at the same time he is High Priest reconciling mankind with their Creator. He is able to raise the dead; he will judge the world. By faith Peter perceived Christ’s glory.
Together the disciples believed; and with Peter as spokesman they testified offering that crucial witness: That this Jesus is the Holy One of God, and not an ordinary man but true God also. All God’s qualities were upon him as God’s Son. He remained sinless, and carried out his task as the Lamb of God, as the Baptist had prophesied. The disciples loved him and revered him, for they knew that his presence meant God’s presence. In the Son they saw him the Father, and learnt that God is love.
