"Then He [Jesus] said to His disciples, 'Therefore I say to you, do not worry about your life . . . ' "
Here is a very big challenge for any of us: not to worry about our lives. I would say that this is pretty much impossible to do, aside from miraculous grace. We "worry about [our lives]" just about as naturally as we breathe air.
But it is highly-liberating to actually *trust* God, and *not* to worry about our lives. It can be done, but it requires real and applied faith. No churchman on earth will ever do this (failure to worry) perfectly; but it really honors God whenever we do it *sincerely*--even though we still have a long way to go.

fluence upon the soul; they dissolve it in love to God. God's judgments make us fear Him, His mercies make us love Him." --Thomas Watson, in "All Things for Good"]
