“I feel lost now! How can there be a loving God?”

The Grace Message with Dr. Andrew Farley

What does it mean to “receive the grace of God in vain”? Why does Paul tell the Corinthians not to teach unclean things? I was a believer, but I got involved in materialism. Now, I feel lost. Why would God make a Devil who would tempt me? How can there be a loving God if there’s so much suffering in the world? What does it mean to ask God to forgive you of all your sins?
