What does the Bible say about the cause of faith?

According to Galatians 3:6-14, the cause of faith lies not in human action but in God's divine initiative. Paul explicitly asserts that Abraham believed God, and this belief was accounted to him for righteousness. Therefore, faith is not generated by our efforts or choices; it is given by God. The Scripture provides a clear narrative that highlights how God preached the gospel to Abraham, enabling him to believe. This underscores the Reformed perspective that faith is a gift from God, ensuring that all glory is directed towards Him rather than human achievement.
