For I have come down from heaven not to do my will but to do the will of him who sent me.
Jesus acknowledges more than once, as a man, His will may differ from the will of the Father. Yet His perfect obedience to the will of God becomes mediation for us, as we prove again and again our lack of obedience. We want to have things our way and try to bend God to our desires.
As John Calvin wrote, “Christ is a pattern of perfect obedience… that all who are His may contend with one another in imitating Him, that they may together respond to the call of God and that their life may exemplify this saying, ‘Lo, I come.'”
And from Dietrich Bonhoeffer: “Being a Christan is less about cautiously avoiding sin than about courageously and actively doing God’s will.”
