The biggest threat to the flock of sheep is predation. We are open preys to large monstrous predators. False shepherds will try to drive us away from the flock but we can discern them. If they do not come in the name of the Master Shepherd, Jesus Christ, or they bear any other name aside from the Lord Jesus, we should not listen to them. If they preach any other savior than our Lord Jesus then we should not listen to them. The evil one seeks to steal from us, kill us and destroy us. He will attempt to steal all our blessings so that we will hate God. He will attempt to kill the slightest hope that we hold on to and destroy the faith that we so value.
