Query: Proof of Angels

This is one of the best books of true stories that I have ever read. This exciting collection of people's encounters with angels serves to remind us that angels DO exist, and that they are DAILY at work in our lives. The Bible says, "Are they [angels] not all ministering spirits sent forth to minister for them who shall be heirs of salvation?" - Hebrews 1:14 This book can serve to strengthen anyone's faith. I enjoyed it so much that it didn't take me long to read it. I highly recommend it.
