47 “I tell you, her sins—and they are many—have been forgiven, so she has shown me much love. But a person who is forgiven little shows only little love.” 48 Then Jesus said to the woman, “Your sins are forgiven.”
49 The men at the table said among themselves, “Who is this man, that he goes around forgiving sins?” 50 And Jesus said to the woman, “Your faith has saved you; go in peace.” (Luke 7:44-50 NLT)
Because God loves us, Jesus paid for our sins to forgive us. Because God forgives us, we can return His love. The more we realize our need for God's love and forgiveness, the more love we give to Him. But if we don't think we need much forgiveness, we don't give that much love back to God or to others.
We are saved by faith to live in peace, to forgive and love one another.
