Many of God's people do not live in the reality that God's face is shining upon them. God loves us more than we can imagine. Nothing will motivate us more than this realization. Even when we have failed Him, He loves us as His dear children.
Jesus is a friend of sinners. He seeks those who go astray and are lost. His heart of love constrains Him to diligently pursue the sinner. He laid down His life for us. When we come to Him in repentance, He accepts and forgives us.
