1 In those days was Hezekiah sick unto death. And Isaiah the prophet the son of Amoz came unto him, and said unto him, Thus saith the Lord, Set thine house in order: for thou shalt die, and not live.3 And said, Remember now, O Lord, I beseech thee, how I have walked before thee in truth and with a perfect heart, and have done that which is good in thy sight. And Hezekiah wept sore.5 Go, and say to Hezekiah, Thus saith the Lord, the God of David thy father, I have heard thy prayer, I have seen thy tears: behold, I will add unto thy days fifteen years.6 And I will deliver thee and this city out of the hand of the king of Assyria: and I will defend this city.7 And this shall be a sign unto thee from the Lord, that the Lord will do this thing that he hath spoken;
In this story Hezekia was sick and Isaiah told him he would die. (That would be shocking news to anyone.) Then Hezekiah prayed for his life to be spared and the Lord answered his prayers, and gave him a sign as a promise. The sign the Lord gives (v7-8) is very interesting.
The promise the Lord gave to Hezekiah was 15 more years of life. The sign was to be that the shadow of the sundial would go back 10 degrees. That might seem like an odd sign to give. A moving shadow. But behind that moving shadow was something very unusual on an astronomical scale. It would look like the sun was moving, but we know it was really the earth that moved, that it slowed imperceptibly, then stopped, and reversed its rotation until it had gone 10 degrees backward, then slowed, stopped, and began rotating in the usual direction again, all without any detrimental inertial effects on the earth’s inhabitants.
Amazing, huh? Yes, and it is also amazing that all that was done for the sake of one man. Doesn’t that almost seem like…overkill? But I suppose that shows just how much the Lord loves the one.
I also realized that the sign was actually meant to teach Hezekiah something about the Lord’s power. Not simply that the Lord could move astronomical bodies hither and yon at will, but that the Lord really did have the power to lengthen Hezekiah’s life. Turning the shadow of the sundial back 10 degrees had the effect of lengthening that day, so Hezekiah was to understand that if the Lord could lengthen one of Hezekiah’s days, He could and would lengthen Hezekiah’s life as promised.
To me this teaches me that the Lord has control over my life span and while I do my part to take care of my body, ultimately the Lord is in charge of how long I live.
