He spoke of his Father consecrating him for this mission of salvation. Why were the religious leaders so upset with Jesus that they wanted to kill him? They charged him with blasphemy because he claimed to be the Son of God. Jesus made two claims in his response: He was consecrated by the Father to a special task and he was sent into the world to carry out his Father's mission.
Jesus challenged his opponents to accept his works if they could not accept his words. One can argue with words, but deeds are beyond argument. Jesus is the perfect teacher in that he does not base his claims on what he says but on what he does.
The word of God is life and power to those who believe. Jesus shows us the way to walk the path of truth and holiness.
And he anoints us with his power to live the gospel with joy and to be his witnesses in the world. Are you a doer of God's word, or a forgetful hearer only?
