One of the post's have already told you that faith is a fruit of the Spirit and you have to be born of the Spirit before you can understand anything that is of a spiritual nature according to 1 Cor 2:10-14. Yes, faith comes by hearing, but you can not hear and understand unless you have already been born of the Spirit.
No verse says one is born again then believes for that idea is in total opposition to what the bible teaches.
Again, Jn 6:45 men of his own free will "cometh to Christ" and not forced by God or unconditionally predetermined by God to come to Christ.
