Actually, I'd first like to see a reference to "Jesus was ALWAYS supposed to come and save us" from Scripture. (I'm not claiming you're wrong, just looking for a reference.)
Genesis 3:22 - "He must not be allowed to reach out his hand and take also from the
tree of life and eat, and live forever."
Revelation 2:7 - He who has an ear, let him hear what the Spirit says to the churches To him who overcomes, I will grant to eat of the tree of life which is in the Paradise of God.'
Revelation 22:19 - and if anyone takes away from the words of the book of this prophecy, God will take away his part from the tree of life and from the holy city, which are written in this book.
Isaiah 59:15&16 - Now the LORD saw, and it was displeasing in His sight that there was no justice. And He saw that there was no man, and was astonished that there was no one to intercede; then His own arm brought salvation to Him, and His righteousness upheld Him.
Zechariah 9:9, Rejoice greatly, O Daughter of Zion! Shout, Daughter of Jerusalem! See, your king comes to you, righteous and having salvation, gentle and riding on a donkey, on a colt, the foal of a donkey.
Isaiah 53:3-7, He was despised and rejected by men, a man of sorrows, and familiar with suffering. Like one from whom men hide their faces he was despised, and we esteemed him not. Surely he took up our infirmities and carried our sorrows, yet we considered him stricken by God, smitten by him, and afflicted. But he was pierced for our transgressions, he was crushed for our iniquities; the punishment that brought us peace was upon him, and by his wounds we are healed. We all, like sheep, have gone astray, each of us has turned to his own way; and the LORD has laid on him the iniquity of us all. He was oppressed and afflicted, yet he did not open his mouth; he was led like a lamb to the slaughter, and as a sheep before her shearers is silent, so he did not open his mouth.
