Throughout the bible we are refferred to as sheep. (And yes, maybe in a stupid way. After all -- we think we know everything.) We are a large flock of sheep, lazily doing very little to help our world.
What else does the Bible say? Peter tells us that we need to, "Control yourselves and be careful!" He warns us that, "The devil, your enemy, goes around like a roaring lion looking for someone to eat." ((1 Peter 5:8-end))
That's pretty scary! We are helpless, dumb, lazy sheep and there is a lion watching us, waiting for one of us to stray too far. When we do, he pounces.
For example, in the African savannah, a herd of zebras are grazing happily. The leader lifts his head, sensing danger -- the musky smell of lions. The lion stalks the herd but does not attack because they are too strong together. Yet when one zebra strays from the herd, the lion pounces on it.
In the same way, we need fellowship with other Christians to make us stronger. Satan will be watching our every move, and if we stray from the Master and from our fellow Christians, we will be attacked.
Then what does Peter tell us? "Refuse to give into Satan by standing stronger in your faith. You know that your Christian family all ove the world is having the same kinds of suffering. And after you suffer a short time, God, who gives all grace, will make everything right. He will make you strong and support you and keep you from falling. He called you to share in his glory in Christ, a glory that will continue forever."
