—1 Kings 22:30-32 (NASB)
Ahab approaches Jehoshaphat on the premise that they’re brothers, that they have the same enemies and family background, and that it’s only fitting that they go out to fight the common enemy together. But when they go into battle Ahab’s true nature is revealed in that he wants Jehoshaphat, the guy with the real biblical faith, to become the focus of the attack. When good Christians make alliances with those who are Christian in name only, not only will the battle be lost, but in the process they’ve made themselves the main target of the enemy.
This pattern has repeated itself throughout the whole of church history even unto this very minute. False brethren will say, “We’re against abortion and you’re against abortion, so let’s form an alliance against abortion together.” It sounds reasonable until you get into battle and the topic changes from abortion to some other point of doctrine on which you both absolutely disagree. Then the well-intentioned find themselves the center target with no support from anyone. Such alliances have been made with the Catholic church, Mormons, and just about every cult and false faith on the planet. You cannot enter into a relationship only agreeing on one or two cultural, political, or economic points.
Ahab was a Jew culturally, he was a Jew ethnically, he was a Jew socially, but he was not a Jew spiritually. He was married to Jezebel, the ultimate spiritual seducer leading everyone to use the things and terms of the One True God to be applied to worshipping something else entirely in His place. Likewise today we have those who claim the label “Christian” or “Evangelical” who actually subscribe to practices far afield from those who can be truly called such. We need to preach to such people, we need to pray for such people, but we are NEVER to enter into fellowship — a personal relationship — with these people. The truth is that they’re not really fellow believers.
—2 Corinthians 6:14 (NASB)
Always bear in mind that the definition of “heresy” is to lay truth alongside error. There is always some truth in what false believers and even cults have to say. But we cannot treat them as fully incorporated members of the body of Christ. Those devoted to the Purpose Driven agenda, the Emergent Church movement, and those entering into partnership with the Catholic church all subscribe to a few beliefs in common with our beliefs, but overall they are in darkness. They cannot be reconciled and heald by us joining in fellowship with them, but loving them enough to hold them accountable to the Truth.†††
