What does the Bible say about saving faith in Christ?

The Bible teaches that saving faith is not merely an acknowledgment of Christ's existence or a belief in His miracles, as seen in John 2:23-25. True faith is a complete entrustment of one's spiritual well-being to Christ alone. This means that it comes from being born again by the Spirit, resulting in a heart that clings to Christ, recognizing Him as the sole source of righteousness. It’s not about mere head knowledge or moral reasoning; rather, it's a divine work of grace that moves an individual to wholeheartedly depend on Christ for salvation.
