Q. WHO CHOOSES?
A. Everyone.
Part 1. Sinners choose to hide and flee from God:
Genesis 3:8 [ESV] And they heard the sound of the LORD God walking in the garden in the cool of the day, and the man and his wife hid themselves from the presence of the LORD God among the trees of the garden.
John 3:19-20 [ESV] And this is the judgment: the light has come into the world, and people loved the darkness rather than the light because their works were evil. For everyone who does wicked things hates the light and does not come to the light, lest his works should be exposed.
Romans 1:18-22 [ESV] For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For his invisible attributes, namely, his eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse. For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. Claiming to be wise, they became fools,
Romans 3:9-12 [ESV] What then? Are we Jews any better off? No, not at all. For we have already charged that all, both Jews and Greeks, are under sin, as it is written: "None is righteous, no, not one; no one understands; no one seeks for God. All have turned aside; together they have become worthless; no one does good, not even one."
Part 2. God chooses to condemn sin:
[Deu 9:5-8 ESV] 5 Not because of your righteousness or the uprightness of your heart are you going in to possess their land, but because of the wickedness of these nations the LORD your God is driving them out from before you, and that he may confirm the word that the LORD swore to your fathers, to Abraham, to Isaac, and to Jacob. 6 "Know, therefore, that the LORD your God is not giving you this good land to possess because of your righteousness, for you are a stubborn people. 7 Remember and do not forget how you provoked the LORD your God to wrath in the wilderness. From the day you came out of the land of Egypt until you came to this place, you have been rebellious against the LORD. 8 Even at Horeb you provoked the LORD to wrath, and the LORD was so angry with you that he was ready to destroy you.
Proverbs 6:16-19 [ESV] There are six things that the LORD hates, seven that are an abomination to him: haughty eyes, a lying tongue, and hands that shed innocent blood, a heart that devises wicked plans, feet that make haste to run to evil, a false witness who breathes out lies, and one who sows discord among brothers.
Ephesians 2:1-3 [ESV] And you were dead in the trespasses and sins in which you once walked, following the course of this world, following the prince of the power of the air, the spirit that is now at work in the sons of disobedience-- among whom we all once lived in the passions of our flesh, carrying out the desires of the body and the mind, and were by nature children of wrath, like the rest of mankind.
Part 3. God chooses to offer forgiveness (even if people will not choose it)
Deuteronomy 30:19-20 [ESV] I call heaven and earth to witness against you today, that I have set before you life and death, blessing and curse. Therefore choose life, that you and your offspring may live, loving the LORD your God, obeying his voice and holding fast to him, for he is your life and length of days, that you may dwell in the land that the LORD swore to your fathers, to Abraham, to Isaac, and to Jacob, to give them." [they did not choose life]
Matthew 23:37 [ESV] "O Jerusalem, Jerusalem, the city that kills the prophets and stones those who are sent to it! How often would I have gathered your children together as a hen gathers her brood under her wings, and you were not willing!
John 3:16-18 [ESV] "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. [the world chose to crucify him rather than believe in him]
1 John 1:9 [ESV] If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.
Part 4. God chooses to save some anyway:
Matthew 16:17 [ESV] And Jesus answered him, "Blessed are you, Simon Bar-Jonah! For flesh and blood has not revealed this to you, but my Father who is in heaven.
John 6:44-45 [ESV] No one can come to me unless the Father who sent me draws him. And I will raise him up on the last day. It is written in the Prophets, 'And they will all be taught by God.' Everyone who has heard and learned from the Father comes to me--
John 10:25-30 [ESV] Jesus answered them, "I told you, and you do not believe. The works that I do in my Father's name bear witness about me, but you do not believe because you are not among my sheep. My sheep hear my voice, and I know them, and they follow me. I give them eternal life, and they will never perish, and no one will snatch them out of my hand. My Father, who has given them to me, is greater than all, and no one is able to snatch them out of the Father's hand. I and the Father are one."
Romans 8:28-30 [ESV] And we know that for those who love God all things work together for good, for those who are called according to his purpose. 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.
Part 5. Because He chose us, we are empowered to choose Him:
John 3:21 [ESV] But whoever does what is true comes to the light, so that it may be clearly seen that his works have been carried out in God."
Ephesians 2:8-10 [ESV] For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast. For we are his workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them.
John 13:34 [ESV] A new commandment I give to you, that you love one another: just as I have loved you, you also are to love one another.
1 Thessalonians 4:9 [ESV] Now concerning brotherly love you have no need for anyone to write to you, for you yourselves have been taught by God to love one another,
Romans 6:16-23 [ESV] Do you not know that if you present yourselves to anyone as obedient slaves, you are slaves of the one whom you obey, either of sin, which leads to death, or of obedience, which leads to righteousness? But thanks be to God, that you who were once slaves of sin have become obedient from the heart to the standard of teaching to which you were committed, and, having been set free from sin, have become slaves of righteousness. I am speaking in human terms, because of your natural limitations. For just as you once presented your members as slaves to impurity and to lawlessness leading to more lawlessness, so now present your members as slaves to righteousness leading to sanctification.
For when you were slaves of sin, you were free in regard to righteousness. But what fruit were you getting at that time from the things of which you are now ashamed? For the end of those things is death. But now that you have been set free from sin and have become slaves of God, the fruit you get leads to sanctification and its end, eternal life. For the wages of sin is death, but the free gift of God is eternal life in Christ Jesus our Lord.
