You responded to the call of the gospel through the Holy Spirit. That is good, and agreeable.
The second question was about conviction. What brought conviction that you even recognized the need to "respond to the call of the gospel through the Holy Spirit?"
These are the kind of questions Calvinists commonly ask, which in their mind proves their doctrine, but does not. When a Calvinist asks why one man is convicted by the Holy Spirit and another is not, the Calvinist has already assumed that Total Depravity is a truth, and that an unregenerate man cannot possibly repent, and MUST be regenerated to have this ability.
But the scriptures show that unregenerate man can be convicted by the word of God.
Jhn 8:3 And the scribes and Pharisees brought unto him a woman taken in adultery; and when they had set her in the midst,
4 They say unto him, Master, this woman was taken in adultery, in the very act.
5 Now Moses in the law commanded us, that such should be stoned: but what sayest thou?
6 This they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with
his finger wrote on the ground,
as though he heard them not.
7 So when they continued asking him, he lifted up himself, and said unto them,
He that is without sin among you, let him first cast a stone at her.
8 And again he stooped down, and wrote on the ground.
9 And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.
These men were not regenerate, in fact they were tempting Jesus so that they could accuse him of sin. Jesus simply responded and said that whosoever among them was without sin, that man should cast the first stone.
That caused these men to reflect on their own lives and whether they had sinned or not. It is notable that the eldest, or oldest men went away first. These men had their whole lives to reflect upon and knew they had sinned against God many times. But eventually even the youngest left.
And note they were convicted by their "own conscience". The word of God can speak to the conscience that every man is born with. All men have a conscience and know right from wrong.
So, this passage proves the Calvinist doctrine of Total Depravity is false and that unregenerate man can indeed be convicted by the word of God.
