The faith to believe is a gift from God which He imparts with the preaching of the gospel.
No good thing dwells in man.
It's God who begins the good work in us.
But the gifts of God are salvation, eternal life, the indwelling of the Holy Spirit, and the variety of spiritual gifts given to each believer.
Believing is from the heart, not from God.
Do you believe that God chooses who will believe?
