It may be true He knew who would reject and accept the gospel. He even knew of Lucifer's rebellion before the angels were created. Of one was of a mind to, you could blame God for every evil under the sun because He created Lucifer.
He did not create anyone to be a vessel of wrath. He created everyone in order to give everyone an opportunity to choose to love God and serve Him.
There is no reason for anyone to at last die the second death except that he has resisted or rejected the salvation already "given" him "in Christ". Christ died for all. He tasted death for every man. 2 Cor.5:14; Hebrews 2:9; Hebrews 2:3; Matt.22:5. (Neglect in the KJV Heb2:3 means despise.)
At Christ's baptism, the Father accepted the human race in Him. Matthew 3:17 Thus He is already "the Saviour of all men" John 4:42. No one ought to doubt that the Lord has accepted him or her in Christ. But Christ is especially the Savior of those who believe. 1 Timothy 4:10 our relationship doesn't depend on us initiating such a relationship, but accepting what Christ had already initiated.
I think of it in terms of God's sovereignty based on His foreknowledge....since the bible says we are "elect according to His foreknowledge". He gives people the opportunity to repent, but if they keep refusing they become hardened...it is like a natural consequence. And the Lord, having long foreknown who would do what and when, has woven it all into His plans/purposes. But I believe there is no doubt we need to humbly acknowledge the Lord's sovereign
right to do with man whatever He wills, as our Creator and Ruler of all that exists in heaven and earth. I dont' want to go too far, we only know in part, but I wonder if where it says He hardens who He will, if that is in a manner of speaking....based on His sovereign rule in the things He allows.
Rom 9:16-23
So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.
For the scripture saith unto Pharaoh, Even for this same purpose have I raised thee up, that I might shew my power in thee, and that my name might be declared throughout all the earth.
Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.
Thou wilt say then unto me, Why doth he yet find fault? For who hath resisted his will?
Nay but, O man, who art thou that repliest against God? Shall the thing formed say to him that formed it, Why hast thou made me thus?
Hath not the potter power over the clay, of the same lump to make one vessel unto honour, and another unto dishonour?
What if God, willing to shew his wrath, and to make his power known, endured with much longsuffering the vessels of wrath fitted to destruction:
And that he might make known the riches of his glory on the vessels of mercy, which he had afore prepared unto glory,
