Max Lucado examines in detail 'love' in 1Cor13. He uses examples from his own life as well as stories from the Bible to explain each point. He explains that love as outlined in 1Cor13 is the love that God has for us and it's this love that we are to show others. To do that, we need to receive God's love and allow this love to overflow to others. I found this book life changing. It brought revelation to my life and helped me to appreciate how amazing God's love is for me.
