I know all the proof texts for the Anti-Calvinist position because for 30 years that was my position. I understand your position completely because it was my position as well. But the scriptures are clear and once a person's eyes are opened to them, there is no going back.
We are depraved people, and that is the simple truth.
Joh 3:19 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. 2Ch 36:16 But they kept mocking the messengers of God, despising his words and scoffing at his prophets, until the wrath of the LORD rose against his people, until there was no remedy.
We cannot know or see the level of our depravity so steeped as we are in it. God sends His prophets and we kill them. The light comes into the world and we kill Him. This is our nature. Our hearts are hardened by God (and by ourselves) with just a loving word from Him. "Don't take the fruit because you'll die." "Sin is crouching at your door, but you must overcome it." "Let my people go so that they might worship me." He is so good and kind. But the truth is, as unbelievers we want to sin and we steel ourselves against Him. And God hardens our hearts with just a simple loving command that is to our benefit, so corrupt are we.
Rom 1:20-21 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.
People know God exist. It isn't that He is hidden away. We just don't want to worship Him. This is the love of God and mankind's depravity. And the kicker to all this is that unless God opens their eyes, man cannot understand the level of their depravity because they are depraved. This is what we want and this is what God has given us.
It is God that must take us by the hand and yank us out of Sodom.
Eph 2:1 And you were dead in the trespasses and sins Eph 2:2 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—
Eph 2:3 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.
Eph 2:4 But God, being rich in mercy, because of the great love with which he loved us,
Eph 2:5 even when we were dead in our trespasses, made us alive together with Christ—by grace you have been saved—
God so loves us that there is a remnant that He saves with His grace and mercy. The real mystery for the believer is why did He grant us His grace and mercy.
