I don't think you have a firm grasp of sin and grace.
What you think doesn't matter. What does is
I was saved when I was 14 years of age. I was drawn and called I was convinced of Christ through His gospel. I had many opportunities to come to Him. He convinced me through conviction. I was convinced that I deserved hell, If I rejected Him any more than I already had. He was not sending me to hell I was already on that path because of my sin and rebellion. I was going to hell willingly because I refused to accept Him as Savior.
God's saved me by grace through faith. This happened because I believed like Paul told the Jailer to do.
Act 16:31 And they said,
Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house. You have deny this scripture because you do not believe the gospel truth.
Calvinist do not believe man has faith before Salvation and they say regular faith isn't going to save anyone. We have to have saving faith according to Calvinist. There is no difference between believing in something. All faith in Jesus Christ saving faith.
The Bible does not say we have to be regenerated first because being regenerated means being saved.. It means being born again.
I do not believe we worship the same God because of your description of God. The God you all claim is no where close to the only God there is. If God is as you claim. Then He is no different than Satan
