We have no time to lose. We know not how soon our probation may close. At the longest, we have but a brief lifetime here, and we know not how soon the arrow of death may strike our hearts. We know not how soon we may be called to give up the world and all its interests. Eternity stretches before us. The curtain is about to be lifted. But a few short years, and for everyone now numbered with the living the mandate will go forth.
