We have only the time allotted by God, and none of us knows when it will run out. Every Christian life runs by His divine timetable and against His divine clock. We do not know how long He will hold open the door of a given opportunity or of our entire time of service. “Be careful how you walk,” Paul counsels, “not as unwise men, but as wise, making the most of your time, because the days are evil” (Eph. 5:16). God gives us many things without limit – His love, His grace, and many others. But His gift of time is strictly measured.
