My comment was about eschatological (end times) viewpoints not predestination but since you brought it up.....

I've never read Calvin. I avoid doing so for just this reason. My position on salvation is from scripture and how God saved me when I didn't want to be saved.

When we are "dead in our sin" it's an act of God that transforms us. "No one seeks after God, no not one"

Saying you have free will to chose God goes against your nature. It's God's grace that saves us, not our own free will. Just like when Jesus raised Lazarus from the grave. Did Lazarus have anything to do with it? No. Did God violate his free will to live? No. That was beyond Lazarus's ability to chose just like us when we are dead in our sin.

I didn't choose God. It was the last thing I wanted at the time. I was a militant athiest and hostile towards God and Christianity. But God chose me anyways, showed me my sin, brought me to repentance, and gave me a heart of flesh to replace my heart of stone. It was a radical transformation on the floor in front of a window. 20 years of drug addiction broken in an unwanted instant. The only thing I contributed to my salvation was the sin that required a savior. My humility knowing that truth and my awe of God's amazing grace is that much more. I hope you come to know that yourself. I won't call you immature in the process however.

The Father I know is not that Father. He predestines no one to damnation. Such a God would not be a Father of love, but a father of abuse.

You forgot that justice is one of His qualities. The real question you should be asking is why He would chose to save any of us. I'd suggest reading The Potter's Freedom to better understand the fact that God makes some vessels to contain His wrath and some to save.

Scripture is clear, God is sovereign over everything including salvation ....
