Have you ever seen a boxing match between a left arm and a right arm of the same person? Does your little finger purposely scratch and hurt your ring finger? If you are cold, does one of your feet try to block out the other foot to get closer to the heater? No, of course not. To even speak of such things seems absolutely ridiculous. But, I tell you, this sort of ridiculous fighting goes on in the Body of Christ all too often.
One of the things I fear most in ministry of any kind is the disunity that the devil is able to create. When disunity prevails, the work of the Lord is destroyed. Satan knows very well that “any kingdom divided against itself will be ruined, and a house divided against itself will fall” (Luke 11:17, NIV).
And seeing how Satan cringes at the thought of the kingdom of God advancing, he does not want the house of the Lord to stand. So he takes those differences that were meant to complete us and uses them as the very thing to divide us. Whether it is differences in theology and doctrine or styles of worship and prayer—any difference you can imagine—Satan will use them to sow seeds of strife and disunity.
This is the reason why God so justly and immediately dealt with anything that hindered the unity of the children of Israel throughout the Old Testament. Whenever God asked His people to go forward, He would first weed out whatever held them back from moving ahead united in heart and mind. In Numbers 16, we read the story of Korah, the man whom the ground opened up and swallowed after he refused to acknowledge Moses as God’s appointed leader. In Numbers 12, God punished the fractionating spirit of Miriam and Aaron. When the 12 spies came back with divided reports about the prospects of taking over the Promised Land, God punished the dissenting 10 spies who had not trusted Him (see Numbers 14).
