When Jesus came and God’s kingdom in him, not only was there to be a change contradicting the world’s system, but at bottom there was to be no less than a change of heart. It does little to no good to change systems or laws when there is no change of heart corresponding.
That week Jesus was telling his disciples that they would all fall away because of what was about to happen to him. Peter denied it emphatically, showing what little he knew. The Lord corrected him, telling him that he would actually deny him three times. Peter then protested that even if he had to die with Jesus, he would never deny him.
We know what happened afterward. In the garden Jesus had told the disciples not only to watch and pray with him, but to pray that they would not fall into temptation. The disciples fell asleep, and then Jesus’ rebuke, wondering that they could not watch with him for one hour. With the warning: “The spirit is willing, but the flesh is weak.”
The Lord had told Peter that Satan had asked permission to sift all the disciples as wheat. But that Jesus had prayed for Peter. With the directive that when Peter would turn back in repentance that he should strengthen his brothers. We know how that happened. Peter does return, and then the Lord asks Peter if he loves him three times. Perhaps the change in the last of that questioning from the verb form of agape to phila love mattered. But Peter broke down in grief. This was a time of deep soul searching and transformation of heart.
Jesus came to give us a new heart. Our hearts are often hard and unmoved. We don’t want to do what we know we ought to do, or we do what we should not because our hearts are unchanged. Scripture tells us that a broken and contrite heart God will not despise. Jesus said that on the outside people can look good, while the inside can be full of evil. White washed tombs with dead people’s bones inside.
I can be slow at heart to believe and obey. It is good when one finds it joyful to obey in love. Jesus came and walked that dreadful way of the cross to give us a new heart. In his high priestly prayer, Jesus prayed just prior to his suffering, “For them I sanctify myself, that they too may be truly sanctified.” This was a setting apart to God in sacrifice, in order that his followers would also be set apart as his followers in the same way. In heart and life.
Paul prayed that the believers might know the depths of God’s love in Jesus, that they might be filled to all the fullness of God. We are being remade in and through Jesus into the very image of God through and through. In calling and in heart.
In the end tradition tells us in keeping with Jesus’ earlier words to Peter, that Peter was to die on a cross, even as his Master, Savior and Lord had died. Peter insisted that he was not worthy, and that therefore he should be so executed on a cross, upside down. A heart which was soft, contrite, sensitive to all that is wrong not only in the world, but in one’s self.
Yes, we need a change of heart. “Change my heart oh God. Make it ever true. Change my heart oh God. May I be like You.” By Jesus and God’s love in him in and through his death for us. Together in Jesus for the world.
