The world has no part with the believers in this work. They cannot discern the motives and principles by which God's people are bound in their relations and dealings with one another. We must be true, loyal soldiers in the army of Jesus Christ. All His followers are to keep step with their Leader. They should never introduce their secrets to, or make confidants of, the enemies of Jesus Christ in regard to their movements or what they purpose to do in their line of action; for it is a betrayal of sacred trusts, and is giving the enemy every advantage. Let the counsel of the people of God be within their own company. The enemies of Christ should not be made familiar with their secrets, while the children of God are kept in ignorance of the very things they ought to know. The secrets of the Lord are with them that fear Him. TM 269.2
The world is the chief enemy of religion. The satanic forces are constantly at work through the world, and those who are professed Christians, yet associated with the world in close fellowship, are so much one in spirit, aims, and principles of working, that they cannot discern between him who serveth God and him who serveth the world. The enemy works constantly to push the world to the front, to be looked upon as superior to those who believe in Jesus, and who seek to be doers of His word. Words of praise and flattery from worldlings are received as sweet morsels, but the judgment of those who love this sort of food is in accordance with the weakness which they show in this direction. Their spiritual life is composed of just the kind of material they feed upon. Their Christian experience is largely dependent on flattery and human appreciation. The fear and love of God are not interwoven in their experience. TM 270.1
How pitiable and sad to see men who have known something of the Spirit of God fall so completely into the arms of the world as to be swayed and influenced by its voice, and depend upon its favors for strength and success! How manifestly such are alienated from Christ, how full of self-confidence, how full of vaunting, of vanity, and how shortsighted in regard to spirituality! How little true discernment have they to distinguish between him who is a child of God, an heir of the kingdom, and him who is a child of the wicked one, who is a child of disobedience, and an enemy of God! TM 270.2
