A man’s spirit sustains him in sickness, but a crushed spirit who can bear? (Proverbs 18:14, NIV)
Alas, ‘tis the woes of winter. At least God has sustained me in my sickness, as much as He will do in health. As much as I can complain and whine about being sick, God still gives me grace and forgiveness to deal with it. (I hope to be better, thank you.) Another thing I cling my hope on is at Jesus during the times I feel spiritually “sick” and kind of “bleh” in my life.
If you mean by “life”, I mean “spiritual” and “normal” life. Call it as you are, but there are times where we bag ourselves in pure-bred sick and icky until we can’t take it anymore. (This is an obvious reference to sin.) We get colds, flu’s, even that thing from swine we can’t name anymore! Overall, God still is working us out in our hearts, yet we do not know how true and certain this statement is.
Overall, how true is God working when we are really sick? I just have a cold. We were, in a deeper sense, sick back out there (needing to avoid euphemisms), called out by God to heal us and change us into what we are now. We still get dirty, as long as we keep fighting the good fight of faith, and He still nurses us back to health. Even if it is every day. Because we always sin every day, it is to say that we need to be checked up every day. Jesus never hesitates to do the job.
