1 Chronicles 12:21-22 And they helped David against the bands of raiders, for they were all mighty men of valor, and they were captains in the army. For at that time they came to David day by day to help him, until it was a great army, like the army of God.
Hebrews 10:25 Not forsaking the assembling of ourselves together, as is the manner of some, but exhorting one another, and so much the more as you see the Day approaching.
A program by National Geographic gives a powerful illustration for us. In the great annual wildebeest migration in Serengeti National Park in Africa a giant herd, thousands of wildebeest, slowly move in groups across the plain. They are invariably followed by stalking lions. But the lions never attack the herd - they simply watch carefully for the stray wildebeest, either careless or seeking greener grass, who separates himself from the larger groups of animals. The isolated wildebeest will become the sudden prey of the lions who attack with lightening speed and ferocity.
In spiritual warfare isolation is equally dangerous, as our enemy roams like a roaring lion looking for separated brethren to prey upon. We all need real relationship and spiritual community for protection against our enemy who is constantly stalking vulnerable prey. It's not enough to simply "go to church". We need to be the community of believers, actively participating in loving, serving, praying, counseling, encouraging, admonishing, eating, rejoicing, weeping, and forgiving as the family of God.
Far too many believers are isolated, and seriously vulnerable to the attacks of Satan. Are you one of them? Do you know someone who is in this dangerous condition? David's army was successful and safe because they were together in mind heart and purpose. Wildebeest, as well, survive when they stick together. Find your spiritual community and be faithful to it. It should not be a formality, but a family reality with a warfare mentality.
