Loving People: How to Love and Be Loved, by Dr. John Townsend.
So many today do not know how to properly love or how to receive love when offered to them. Furthermore, it is an antidote to legalism, rule centered living, and a door to help one live and walk in the Spirit of love.
SO far no one who has read this book has come back to tell me that it did not help them in some way or another.
