For God so loved the world, that he gave his only Son, that whoever believes in him should not perish but have eternal life. For God did not send his Son into the world to condemn the world, but in order that the world might be saved through him. Whoever believes in him is not condemned, but whoever does not believe is condemned already, because he has not believed in the name of the only Son of God.
John 3:16-18 (ESV)
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.
