GINOLJC, to all.
Addressing the OP, and not having read all of the post.
The question is asked, did God forsake the son on the cross. answer, NO. as a matter of fact, when Jesus said that it is finished, yes, on Sin in the world, but the glory and, the wonderful work of God just began. after preaching to the spirits in prison, then the day of Pentecost. this was not a end, but the begining of something wonderful.
the Op hit at it and a few other, but consider this. as said, "God cannot look upon sin",
this is bared out in Isa chapter 59, read this chapter real good. the word forsaking, (forsook), means to abandon, desert, leave. or note this "sacrificed". the present of the Father in that body, ( came out of the son, because, 2 Corinthians 5:19a "To wit, that God was in Christ, reconciling the world unto himself, not imputing their trespasses unto them".), because his "WORK" was "FINISHED". now the sins of the whole world will be laid on him, (Jesus the diversity, the "SON", the G2758 κενόω kenoo of God himself).
This word forsook is interesting. Forsook , or forsaking is the act of, or the allowing of one to be sacrifice. Note, to clearly see this, another word, or some synonyms words for forsook as said are, renounced, relinquished, “sacrificed”. Sacrificed is the word we are looking for. For the Lord God did provide for himself a sacrifice, (a lamb). Genesis 22:8 "And Abraham said, My son, God will provide himself a lamb for a burnt offering: so they went both of them together”. And who is this LAMB?, God, himself diversified in flesh. John 1:29 "The next day John seeth Jesus coming unto him, and saith, Behold the Lamb of God, which taketh away the sin of the world". John 1:35 "Again the next day after John stood, and two of his disciples; 36 And looking upon Jesus as he walked, he saith, Behold the Lamb of God!"
and this is bared out in Hebrews 9:26. "For then must he often have suffered since the foundation of the world: but now once in the end of the world hath he appeared to put away sin by the sacrifice of himself”. Also again, proof of Jesus preexistence. God cannot dwell in an unclean place, and the scripture is clear, God will never forsake you, nor leave you, read Hebrews 13:15. and reading the whole chapter of Isa, the entire book is worth reading, but Jesus the lamb of God, was made/design to suffer, even the death of the cross. Philippians 2:5 " Let this mind be in you, which was also in Christ Jesus: 6 Who, being in the form of God, thought it not robbery to be equal with God: 7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men: 8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross".
upon that death, it released, or relinquished, (that's what forsook means), the full power and attributes of God in human form. Glory to Jesus. No more blood to hinder the Power of God. now the same eternal Spirit, that is, and was, is now to come, the Holy Spiritis in full power in a BODY. Jesus is Spirit in Glorified form. now Jesus/God/Spirit is fully diverse in heaven as well as on earth, (the model prayer "thy Kingdom con, as in heaven as on earth"). 1 Corinthians 12:4 "Now there are diversities of gifts, but the same Spirit". in his final administration, this process of forsooking was to give us the same power he had, WITHOUT MEASURE. John 14:12 "Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater [works] than these shall he do; because I go unto my Father". that's why we have the ministering Gifts which was poured out on Pentecost. all because of his, "forsaking", which is a GOOD THING. as the apostlr Peter said, Acts 2:32 "This Jesus hath God raised up, whereof we all are witnesses. 33 Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear". which takes us to the last dispensation of GRACE. the preaching of the Gospel. the ongoing work of the ministry, world redemption. Ephesians 4:11 "And he gave some, apostles; and some, prophets; and some, evangelists; and some, pastors and teachers;12 For the perfecting of the saints, for the work of the ministry, for the edifying of the body of Christ: 13 Till we all come in the unity of the faith, and of the knowledge of the Son of God, unto a perfect man, unto the measure of the stature of the fulness of Christ. 14 That we henceforth be no more children, tossed to and fro, and carried about with every wind of doctrine, by the sleight of men, and cunning craftiness, whereby they lie in wait to deceive; 15 But speaking the truth in love, may grow up into him in all things, which is the head, even Christ".
there is more to this "forsaking" of the Son on the cross, but that's for more topic to cover.
