A workers who quit are no longer subordinate. A soldier who disobeys is insubordinate. Government officials who refuse to obey orders quit before they are fired.
God by definition cannot be under authority and Jesus is God. Philippians 2 is not about Jesus ceasing to be God. It is about Jesus revealing that God is Love. If it were about Jesus ceasing to be God then God is not Love.
Matthew 20:28
28 Even as the Son of Man came not to be served, but to serve, and to give His life as a ransom for many.
Dale, please tell me that you do not think that Jesus, Who is God, is not free, How can you say that God is not free? Why would He bring the possibility up that there might be another way if He had no choice in the matter?.
Of course Jesus did not want to die on the Cross. No one in his right mind would want to do that. No one in his wrong mind would want to do that. And Jesus was in His right mind. He knew very well what He was doing.
Please remember that He predicted His death after Peter confessed that He was the Messiah, and then strongly rebuked Peter when he tried to say that it would not happen.
Jesus did not do it for Himself, even for His Joy. Jesus did not do it for the Father, even though it was the plan of the Father and the Son. Jesus did it for you and me β period. When you take Love out of the Cross, you lose the Good News of Jesus. Please do not allow the Legalists like Wayne Grudem do that.
