What does the Bible say about grace and belief?

The scripture makes it clear that our belief in the gospel is purely a result of God's grace. In John 3:27, it is stated that, 'A man can receive nothing, except it be given him from heaven.' This reflects the profound truth that our faith and even our desire to turn to God come not from our own volition but through God’s empowering grace. Such grace transforms our hearts, enabling us to comprehend and accept the gospel’s truth, as seen in Ephesians 2:8-9, where we learn that we are saved by grace through faith, which is itself a gift from God.
