The problem with perseverance and election are that they logically and inevitably lead to a God that has created beings in His own likeness for the purpose of eternal destruction. That is not the God of the Bible, and those are not Biblical doctrines.
Depends on which verses one reads, or reads around.
Those things that God has ordained include also the eternal salvation of His people, thus leaving the rest of mankind eternally damned. In
Romans 9:13, Paul uses the example of Jacob and Esau to demonstrate that salvation and damnation are the results of His sovereign choice. From eternity past, God permitted Esau’s (and the rest of humanity’s) fall into destruction.
The old testament God didn't go anywhere, or get replaced by the new testament. He is the same forever. Still hates sin, sinners, the wicked, evil, Satan, et al, and, even in the new testament "
our God is an all-
consuming fire."(Hebrews 12:29). The new testament declares those that will escape His wrath are the ones granted grace through Christ, leading to holiness that will not be judged. Thus they will not experience these other new testament declarations: "the elements will be dissolved in the fire, and the earth and its works will not be found.
Since everything will be destroyed in this way, what kind of people ought you to be? You ought to conduct yourselves in holiness and godliness" (2 Peter 3:10-11) and "the present heavens and earth are reserved for fire, being kept for the day of judgment and destruction of the ungodly." (2 Peter 3:7)
Again:
Romans 9:14–24
14 What shall we say then? Is there injustice on God’s part? By no means! 15 For he says to Moses, “I will have mercy on whom I have mercy, and I will have compassion on whom I have compassion.” 16 So then it depends not on human will or exertion, but on God, who has mercy. 17 For the Scripture says to Pharaoh, “For this very purpose I have raised you up, that I might show my power in you, and that my name might be proclaimed in all the earth.” 18 So then he has mercy on
whomever he wills, and he hardens
whomever he wills.
19 You will say to me then, “Why does he still find fault? For
zwho can resist his will?” 20 But who are you, O man, to answer back to God? Will what is molded say to its molder, “Why have you made me like this?” 21 Has the potter no right over the clay, to make out of the same lump one vessel for honorable use and another for dishonorable use? 22 What if God, desiring to show his wrath and to make known his power, has endured with much patience
vessels of wrath prepared for destruction, 23 in order to make known the riches of his glory for vessels of mercy,
which he has prepared beforehand for glory
Vessels are made and prepared and fitted for one particular end or another. Will one of us tell Him what He may or may not do, or should or should not do, with His creation?
