So then you don't think God could cause a person to believe????
It all depends on what you mean by the word "cause". I absolutely believe God caused me to believe the gospel, but when I say the word "caused" I do not mean what you say when you say "caused".
Paul asked how any man could believe unless he has heard of Jesus.
Rom 10:14 How then shall they call on him in whom they have not believed? and
how shall they believe in him of whom they have not heard? and
how shall they hear without a preacher?
Notice that three times in this verse Paul asks "How?". Paul is directly addressing ABILITY here. First, he asks how any man can call on Jesus unless he believes on Jesus. This is simple and logical, if a man truly believes the word of God he will call on Jesus to save him. If the man does not believe the gospel, he will not call on Jesus. Therefore it is impossible to sincerely call on Jesus unless you truly believe he is the Son of God who died for our sins and rose from the dead. If you do not believe Jesus rose from the dead and is God, it would be foolish to call on him. Nobody calls on a dead man.
Next, Paul simply asks how any man can believe on Jesus unless he has heard of him. Now here you go, Paul is answering HOW a person comes to believe on Jesus right here. Paul does not mention ONE WORD about the necessity to be supernaturally regenerated to have the ability to believe. If there was any place in all of scripture to answer that question, this verse would be the place to do that. But Paul simply implies that a person must HEAR of Jesus to believe. This is confirmed by his next question when he asks how any man shall hear unless a preacher tells him of Jesus.
If a preacher had not told me about Jesus and that he was the Son of God and died for my sins, it would have been impossible for me to believe on Jesus. No man can possibly believe what he has never heard and does not know.
I also believe that the natural man would never conceive of the gospel on his own. This is obvious when you see people, like tribes in the jungles who have never heard the scriptures. They all conceive of a god of their own making, an idol. And men always believe they are saved by doing good works for this god that pleases him. Thus they give sacrifices and offerings, etc...
So, no man in his natural man would ever conceive of the gospel, and therefore could never believe on Jesus.
It is because God has sent prophets and preachers into the world to reveal his word that I (and you) came to know the gospel. By this God ENABLED me to believe. He did not force me, I had to decide for myself if God's word was true and make that decision to trust Jesus.
Nevertheless, I could not have believed unless God revealed the gospel to me. In this sense God caused me to believe.
Paul shows how we believe in Romans 10:14, we believe by HEARING the gospel. Hearing the gospel enables us to believe, and in a sense it causes us to believe, because the word of God convicts and convinces us to believe. But God does not impose faith on us, we must choose to believe the gospel of our own free will.
Paul numerous times said he persuades men. This is how we come to believe.
2 Cor 5:11 Knowing therefore the terror of the Lord,
we persuade men; but we are made manifest unto God; and I trust also are made manifest in your consciences.
Acts 19:8 And he went into the synagogue, and spake boldly for the space of three months, disputing and
persuading the things concerning the kingdom of God.
Acts 28:23 And when they had appointed him a day, there came many to him into his lodging; to whom he expounded and testified the kingdom of God,
persuading them concerning Jesus, both out of the law of Moses, and out of the prophets, from morning till evening.
God uses the foolishness of preaching the word of God to persuade men. God does not force or impose anyone to believe. God convinces men to believe. There is a subtle, but important difference.
