No, unfortunately you're the one who doesn't understand "the issue", plus, neither do you read nor comprehend very well. In my post I said that God did it all? What part of "all" didn't you get? Perhaps your problem is that you lack comprehension of what belief actually is? Belief is in coming to the profound realization and complete acceptance in one's heart, that the gospel of Jesus Christ - and all in it - without doubt, is indeed true and came from God - most notably and importantly - a belief that Christ alone is THE Savior (you'll probably need to spend time trying to figuring out what that means if you can). In order to believe, one must first become saved with belief a byproduct of it - belief not bringing salvation but coming from it. It is "all" given by God as a completely free gift from His exceedingly great mercy and grace though Jesus Christ - and unless saved no one CAN come to true belief.
The below verses demonstrate how someone comes to belief - however, as a Christian, you should already know this (but you don't, or you wouldn't have asked). There are other similar verses, but these should suffice you for now.
[Phl 1:29 KJV] 29 For unto you it is given in the behalf of Christ, not only to believe on him, but also to suffer for his sake;
[Jhn 6:29 KJV] 29 Jesus answered and said unto them, This is the work of God, that ye believe on him whom he hath sent.
