A double minded man is unstable in all his ways. James 1:8. TDG 240.1
There are many who would serve Christ provided they could serve themselves also. But this cannot be. The Lord will not accept cowards in His army. There can be no dissembling. Christ's followers must stand ready to serve Him at all times and in every way that may be required. God will accept only true-hearted, level-headed, all-round men. “He that is not with me is against me,” Christ declared; “and he that gathereth not with me scattereth abroad” (Matthew 12:30). TDG 240.2
Many have tried neutrality in a crisis, but they have failed in their purpose. No one can maintain a neutral ground. Those who endeavor to do this will fulfill Christ's words, “No man can serve two masters: for either he will hate the one, and love the other; or else he will hold to the one, and despise the other. Ye cannot serve God and mammon” (chap. 6:24). Those who begin their Christian life by being half and half, whatever may be their intentions, will at last be found enlisted on the enemy's side. TDG 240.3
Double minded men and women are Satan's best allies. Whatever favorable opinion they may have of themselves, they are dissemblers. All who are loyal to God and the truth must stand firmly for the right because it is right. To yoke up with those that are unconsecrated and yet be loyal to the truth, is simply an impossibility. We cannot unite with those who are serving themselves, who are working on worldly plans, and not lose our connection with the heavenly Counsellor. We may recover ourselves from the snare of the enemy, but we are bruised and wounded, and our experience is dwarfed. “Know ye not that the friendship of the world is enmity with God? whosoever therefore will be a friend of the world is the enemy of God” (James 4:4). TDG 240.4
“He that loveth his life shall lose it” (John 12:25). When a man loses the shield of a good conscience, he knows that he has lost the cooperation of heavenly angels. God is not working in him. Another spirit inspires him. And to be an apostate, a traitor to the cause of God, is much more serious than death; it means the loss of eternal life.—Manuscript 87, August 19, 1897, “All That Will Live Godly in Christ Jesus Shall Suffer Persecution.” TDG 240.5
