Faith is the essential spiritual requirement to receive eternal life, according to John 3:16. But what exactly is saving faith? We must know and agree with the facts of the gospel that are explained in the Bible. Additionally, we must commit ourselves to Christ, asking Him for His gift of love and mercy, entrusting ourselves to Him. Although we may only have a "scrap of faith" mixed with some unbelief, God invites us to put our faith in Christ and find forgiveness and grace.
