Ridiculous. Parents are sinning if they worry about their sick children? Big hurricane coming to shore, ok to worry about that? Facing chemo or some other traumatic medical procedure? A good friend of mine died suddenly of a heart attack last year at age 51. His widow is devastated and worried about raising their 3 kids without him. I could go on.
Sure, cause worry accomplishes to much.
Really. If you are trusting God for the best outcome, what is there to worry about?
And for a believer, the worst thing that the world considers, which is dying, is not the worst thing that will ever happen to that person.
We’re not necessarily going to like everything that happens or be glad for it, but worrying does nothing but add stress to the person worrying.
