I want us to take our perception we have of the God and the Old Testament and put it in the back of our mind. Yes, I said, put it in the back of our mind and then try not to think about it as we explore the following text. By the way, the following Text is written in the form of a song.
Behold! My Servant whom I uphold,
My elect One in whom My soul delights!
I have put My Spirit upon Him;
He will bring forth justice to the Gentiles. Isaiah 42:1
My Servant is a designation for the pre-incarnate Christ as we see in Isaiah 41:1 and confirmed in Matthew 12:18. So it would appear this song is being sung by someone and they are singing to someone and the subject of the song is the pre-incarnate Christ. The key to who is singing comes in the second word which is My. So God the Father is singing this song to us about His Servant which is the pre-incarnate Christ. The Servant, (pre-incarnate Christ) is the God Elect One in whom My soul delights. God is saying I enjoy spending time, having a friendship with and companionship with My Elect One. God the Father is saying “in My Chosen One, My soul delights to be with. He has a great burden to bear and so I have put My spirit upon Him. This great burden is to bring forth justice to the Gentiles.
God is so concerned with the mission that His chosen has been given, that God enlists the third member of the Godhead to descend upon Him, because He will bring brining justice to the Gentiles. His Servant the Chosen of God has been asked to carry justice to the Gentiles in the form of salvation and because the mission is so dangerous, He has set His Spirit upon Him, to guide and strengthen Him while the Servant is on His mission to bring justice to the world.
This song sung by the Heavenly Father is sung to the sons of men, telling them that the pre-incarnate Christ is coming in the form of a servant to show justice in a world lacking justice.
Now does God the Father you see singing to his earth children sound like the tyrant we have pictured in the Old Testament. Instead, we see a Heavenly Father that is full of love and goodness wanting to redeem a fallen world to himself.
