"The hope of victory will do much to strengthen one almost exhausted in battle; the desire to reach home invigorates the frame of the weary traveler. So it is with the Christian. In persecution, and sickness, and bereavement, he may be ready to sink under his burdens. The hands fall, and the knees tremble, and the heart sinks within us. But confidence in God, and the hope of heaven, and the assurance that all this is for our good, will reinvigorate the enfeebled frame, and enable us to bear what we once supposed would crush us to the dust. A courageous mind braces a feeble body, and hope makes it fresh for new conflicts."
