Matthew 27:46 And about the ninth hour Jesus cried with a loud voice, saying, Eli, Eli, lama sabachthani? that is to say, My God, my God, why hast thou forsaken me?
A person in the after life that was not in the truth concerning God,will be separated from Him forever,and that is a terrible feeling that is worse than a person that is an atheist on earth right now,for there is still some comfort.
Jesus is God manifest in the flesh,God and man in harmony.
The only thing that makes sense is it was the man Christ Jesus that cried out,My God why did you forsake Me.
Jesus is the Lamb that takes away the sins of the world,and the sins were laid upon Him,and then when He was buried,aid down those sins.
It could be that when the sins of the world were laid upon Him,He felt what is was like to separated from God,but it was only a feeling,for Jesus said the Father will never leave Him,so the Father would of not turned His back on His Son,for He is innocent,but the man Christ might have felt what it was like to be separated from God,because the sins of the world were laid upon Him,although He was not separated from God.
I do not now what else to say concerning it,for Jesus knew He had to go to the cross,and die to save humanity,so He would not say,My God why did you forsake me,concerning that,so the only thing that I can think of is it is the man Christ Jesus that felt temporarily separated from God,for the sins of the world were laid upon Him.
But after Jesus said,My God why did you forsake Me,He then said,it is finished,Father in to your hands I commend My Spirit,so He knew the Father did not actually forsake Him,so it must of only been a feeling that the man Christ Jesus never felt before,because He took away the sins of the world.
