2 Samuel 3:18

Perhaps there is now a "shy, solitary serious thought," in your heart about becoming a Christian. If you let it alone, it may fly away like a bird through a cage-door left open, and may never come back. Or else a crowd of business cares and plans, or perhaps a host of social invitations will flock in, and the good thought be smothered to death. You have smothered just such blessed thoughts before. The thought in your heart is to become a Christian now, and the great bells ring out, "Now is the accepted time: behold, now is the day of salvation." No soul was ever yet saved, and no good deed was ever done to-morrow. Be careful lest tomorrow shall find you beyond the world of probation!
(Theodore L. Cuyler, D. D.)
