Much depends on the unceasing activity of those who are true and loyal, and for this reason Satan puts forth every possible effort to thwart the divine purpose to be wrought out through the obedient. He causes some to lose sight of their high and holy mission, and to become satisfied with the pleasures of this life. He leads them to settle down at ease, or, for the sake of greater worldly advantages, to remove from places where they might be a power for good. Others he causes to flee in discouragement from duty, because of opposition or persecution. But all such are regarded by Heaven with tenderest pity. To every child of God whose voice the enemy of souls had succeeded in silencing, the question is addressed, "What doest thou here?" I commissioned you to go into all the world and preach the gospel, to prepare a people for the day of God. Why are you here? Who sent you?
