what about the one whom the Father set apart as his very own and sent into the world? Why then do you accuse me of blasphemy because I said, ‘I am God’s Son’?
“set apart” = hagiazo = to be separated from profane things and dedicated to God, to be sanctified.
“sent” = apostello = to be ordered to go to a place appointed by the sender. This is the root word for “apostle”. Jesus did not come to earth of His own volition; He was appointed by the Father to come.
Jesus uses scripture to form an argument in the exact manner of the scribes and Pharisees. He is not classing Himself with men; His argument is of the “how much more” variety. He is meeting them on their own ground. He is saying that if those who received an indirect commission from God were so much His representatives as to be called “gods,” then how much more should one who has received a direct and personal commissioning from the Father be allowed to call himself the “Son of God”. McGarvey states it thus: “If it was not blasphemy to call those gods who so remotely represented the Deity, how much less did Christ blaspheme in taking unto himself a title to which he had a better right than they, even in the subordinate sense of being a mere messenger.” (TFG)
