What does the Bible say about believing in Christ?

In the Gospel of John, particularly in John 12:39, we learn about the nature of belief in Christ. The verse states, 'Therefore they could not believe.' This indicates that belief is not simply a matter of human will but rather an act of divine grace. The inability to believe is a result of God’s sovereign choice, which highlights the profound truth that faith is a gift bestowed by God, rather than a result of human effort or decision. Such understanding aligns with the doctrine of Total Depravity which teaches that due to the fall, humans are unable to come to God on their own. Therefore, the act of believing in Christ is intrinsically linked to God's enlightening of a person's heart, enabling them to see and accept the truth of the Gospel.
