Too often, we give God only the tired remnants of our time. If Jesus Christ had given us only the remnant of His time, we would all be on our way to that darkness that knows no morning. Christ gave us not the tattered leftovers of His time; He gave us all the time He had. But some of us give Him only the leftovers of our money and of our talents and never give our time fully to the Lord Jesus Christ who gave us all. Because He gave us all, we have what we have; and He calls us as He is, so are we in this world. (1 John 4:17)
