One thing I can add for thought.
If the choice of salvation is ours. If it is we that do the choosing, then we also have the power to unchoose. There is NO security of salvation then.
If God does the choosing, it is a lock. Gods word is golden. Can anyone find instances of God choosing some and not others in the Bible?
Well that begs further thought, will cause a headache and the words, “but that is not fair”............
Then you get into the debate between Calvin and Arminius.
Eph 2:8
Eph 2:8
(8) For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Both CHARIS (Grace) and PISTIS (faith) are in the feminine, while the demonstrative pronoun HOUTOS (”this”) is in the neuter gender. The near demonstrative pronoun refers to neither grace, nor faith, but to the entire idea of salvation.
Romans 9 is all about God choosing some and not others. Paul even anticipates the "that is not fair" question (You will say to me then, “Why does he still find fault? For who can resist his will?”) and then answers it (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?” 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?)
Yup
Romans 9:10 And not only so, but also when Rebekah had conceived children by one man, our forefather Isaac, though they were not yet born and had done nothing either good or bad—in order that God’s purpose of election might continue, not because of works but because of him who calls— 12 she was told, “The older will serve the younger.” 13 As it is written, “Jacob I loved, but Esau I hated.”
