The Bible is full of stories of angels acting as messengers of God as well as helping people here on Earth. The idea of guardian angels is popular throughout modern culture, and many people believe in them. There is indeed Biblical basis for this belief (see a brief discussion of Matthew 18:10 here). And we're seeing personal proof of this in our own church.
My church is in a small city in northwestern Georgia. Last Fall we built a new building and ever since then we have felt that we are in a spiritual battle. Things have not gone smoothly and people within our congregation have come under one challenge after another. We haven't grown as quickly as we had expected and hoped, despite filling a niche not really seen in our community. It has really seemed like Satan has been having an active hand against us, trying to prevent us from reaching more people.
But in the last few weeks we have been getting encouragement and truly believe that God is letting us see into the spiritual world a bit. There have been some strange occurences in our church....stereos will come on and off. People will see things out of the corner of their eyes. And more than one person has heard the sounds of wings flapping even when they are alone in the building. These things have been noticed by children and adults, and only recently have people been sharing stories with each other. At first it was rather spooky, but the more that happens the more we are really convinced that angels are around us and God is protecting us for something great.
If you're discouraged or feel like everything's going against you, stop for a minute. Look and listen for subtle signs. God loves us all so much that he has angels out there to fight the battles we aren't even aware of. One is out there to protect you. Pray, and your sight may be opened.
