Thus it is with the sinner who, knowing his unworthiness, has entered the Master's vineyard at the eleventh hour. His time of service seems so short, he feels that he is undeserving of reward; but filled with joy that God has accepted him at all. He works with a humble, trusting spirit, thankful for the privilege of being a co-worker with Christ. This spirit God delights to honor.
