But that ye may know that the Son of man hath power upon earth to forgive sins, (He said unto the sick of the palsy,) I say unto thee, Arise, and take up thy couch, and go into thine house. And immediately he rose up before them, and took up that whereon he lay, and departed to his own house, glorifying God. – Luke 5:25

The man’s healing was proved by his obedience. Openly to all onlookers an active obedience became indisputable proof of the poor creature’s restoration. Notice, our Lord bade him rise-he rose; he had no power to do so except that power which comes with divine commands. He rose, for Christ said “Rise.” Then he folded up that miserable palliasse-the Greek word used shows us that it was a very poor, mean, miserable affair- he rolled it up as the Savior bade him, he shouldered it, and went to his home. His first impulse must have been to throw himself down at the Savior’s feet, and say, “Blessed be Thy name;” but the Master said, “Go to thy house;” and I do not find that he stayed to make one grateful obeisance, but elbowing the crowd, jostling the throng with his load on his back, he proceeded to his house just as he was told, and that without deliberation, or questioning. He did his Lord’s bidding, and he did it accurately, in detail, at once, and most cheerfully. Oh! how cheerfully; none can tell but those in like case restored. So, the true sign of pardoned sin, and of paralysis removed from the heart, is obedience. If thou art really saved thou wilt do what Jesus bids thee; thy request will be, “Lord, what wilt Thou have me to do?” and that once ascertained, thou wilt be sure to do it…Open, careful, prompt, cheerful obedience to Christ, becomes the test of the wonderful work which Jesus works in the soul. ~ C.H. Spurgeon
