What does it mean that belief is a gift from God?

In Scripture, particularly in John 1:12-13, believers are described as those who have received the power to become children of God, emphasizing that their ability to believe comes from divine origin rather than their own will or efforts. This illustrates the Reformed understanding that faith itself is a gift from God, aligning with the doctrine of total depravity, where humans are unable to come to God without His enabling grace. Therefore, belief is not a matter of human decision but a spiritual awakening from God, demonstrating His sovereignty in salvation. This highlights the core tenet of sovereign grace—that it is God who initiates, enables, and sustains our faith.
