Ex 33:19, Ps 3:8, Ps 62:7, Jonah 2:9, Eph 2:8
God has mercy on those who are to be saved and saves them by making them believe in Jesus as the Christ. Salvation is not received through our zeal or our will. (Rom 9:14-16, Ex 33:19, Eph 2:8)
Rom 9:14 What shall we say then? Is there unrighteousness with God? God forbid. 15 For he saith to Moses, I will have mercy on whom I will have mercy, and I will have compassion on whom I will have compassion. 16 So then it is not of him that willeth, nor of him that runneth, but of God that sheweth mercy.
Ex 33:19 And he said, I will make all my goodness pass before thee, and I will proclaim the name of the Lord before thee; and will be gracious to whom I will be gracious, and will shew mercy on whom I will shew mercy.
Eph 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Salvation belongs to God. (Ps 3:8, Ps 62:7, Jonah 2:9)
Ps 3:8 Salvation belongeth unto the Lord: thy blessing is upon thy people. Selah.
Ps 62:7 In God is my salvation and my glory: the rock of my strength, and my refuge, is in God.
Jonah 2:9 But I will sacrifice unto thee with the voice of thanksgiving; I will pay that that I have vowed. Salvation is of the Lord.
Even the wicked are made evil by God. (Rom 9:17-18)
Rom 9:17 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. 18 Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.
