I have found this to be very true and very powerful in my life. When I spend time thinking about how God loves me, my heart is defintiely filled with love for Him! psalm 48:9
I think the translation of the NIV in Luke 7:47 could be better. The comparison that Jesus is making requires the phrase, "for she loved much" to be "therefore she loved much". He is saying that she loved much because she was forgiven much, not that she was forgiven much becasue she loved much.
