At Issue - Illness

Isaiah 38:15-19
New International Version (NIV)

15 But what can I say?
He has spoken to me, and he himself has done this.
I will walk humbly all my years
because of this anguish of my soul.
16 Lord, by such things people live;
and my spirit finds life in them too.
You restored me to health
and let me live.
17 Surely it was for my benefit
that I suffered such anguish.
In your love you kept me
from the pit of destruction;
you have put all my sins
behind your back.
18 For the grave cannot praise you,
death cannot sing your praise;
those who go down to the pit
cannot hope for your faithfulness.
19 The living, the living—they praise you,
as I am doing today;
parents tell their children
about your faithfulness.

Sometimes we need a wake-up call to remind us what’s important. Hezekiah’s call came in the form of a terminal illness. Seeing that his life was about to end, he was reminded that life is a gift. He realized that life is meant to be lived fully by walking humbly before God, praising him and speaking of his faithfulness to others. God gave Hezekiah 15 more years to live, and Hezekiah chose to make the most of that time. It’s hard enough to remember what’s truly important in life; it’s even harder to choose what’s important in life and to live with that in mind.
