My good Friday preaching the gospel message of salvation! 

1 Corinthians 1:21 New King James Version 21 For since, in the wisdom of God, the world through wisdom did not know God, it pleased God through the foolishness of the message PREACHED to save those who believe.

Jesus is Lord God Almighty clothed in unsinful humanity and He is the author of (eternal life) to all who trust Him alone for salvation. This means that saving repentance is realizing that you are a sinner deserving of God's just punishment in Hell and turn (repent) from whatever you trusted in before, if indeed you trusted in anything; to trusting in the person and finished work of Christ (alone) for salvation.
