God is Sovereign

No one can come to Me unless the Father who sent me draws him. John 6:44

For those whom He foreknew He also predestined to be conformed to the image of His Son, in order that He might be the firstborn among many brothers. And those whom He predestined He also called, and those whom He called He also justified, and those whom He justified He also glorified. Romans 8:29-30

Even as He chose us in him before the foundation of the world, that we should be holy and blameless before Him. In love He predestined us for adoption to Himself as sons through Jesus Christ, according to the purpose of His will, to the praise of his glorious grace, with which He has blessed us in the Beloved. Ephesians 1:4-6

In Him we have obtained an inheritance, having been predestined according to the purpose of Him who works all things according to the counsel of His will, so that we who were the first to hope in Christ might be to the praise of His glory. Ephesians 1:11-12

For we know, brothers loved by God, that He has chosen you. 1 Thessalonians 1:4

Therefore, brothers, be all the more diligent to confirm your calling and election, for if you practice these qualities you will never fall. 2 Peter 1:10

God is sovereign, but Man is still responsible

But to all who did receive him, who believed in his name, he gave the right to become children of God. John 1:12

For God so loved the world, that He gave His only Son, that whoever believes in Him should not perish but have eternal life.   For God did not send His Son into the world to condemn the world, but in order that the world might be saved through Him.  Whoever believes in Him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God. John 3:16-18

If you confess with your mouth that Jesus is Lord and believe in your heart that God raised Him from the dead, you will be saved.  Romans 10:9

“And if it is evil in your eyes to serve the Lord, choose this day whom you will serve…”. Joshua 24:15

“If anyone thirsts, let him come to Me and drink.  Whoever believes in Me, as the Scripture has said, ‘Out of his heart will flow rivers of living water.’” John 7:37-38

Both are true and harmonious: God is fully sovereign, and man is fully responsible for his decisions.

All that the Father gives me will come to me, and whoever comes to me I will never cast out…And this is the will of him who sent me, that I should lose nothing of all that he has given me, but raise it up on the last day.  For this is the will of my Father, that everyone who looks on the Son and believes in him should have eternal life, and I will raise him up on the last day.        John 6:37-40

Therefore, my beloved, as you have always obeyed, so now, not only as in my presence but much more in my absence, work out your own salvation with fear and trembling, for it is God who works in you, both to will and to work for his good pleasure.         Philippians 2:12-13

They stumble because they disobey the word, as they were destined to do.         1 Peter 2:8

As for you, you meant evil against me, but God meant it for good, to bring it about that many people should be kept alive, as they are today.           Genesis 50:20

But I will harden Pharaoh’s heart…but when Pharaoh saw that there was a respite, he hardened his heart and would not listen to them….         Exodus 7:3; 8:15

What then shall we say? Is God unjust? Not at all! 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 It does not, therefore, depend on human desire or effort, but on God’s mercy.               Romans 9:14-16

Brothers and sisters, my heart’s desire and prayer to God for the Israelites is that they may be saved.                Romans 10:1
