I, on the other hand, had to have lessons years ago on "casting." Celebrating in Serenbe, GA as the "Baby" of our group turned 60, we all gave it a try. I didn't learn much but it was so fun exploring "the "high church" of fishing which fly-fishing has been labeled. (Fishing gear hard to see but we did have some. It came with an instructor.)
Nowadays, "casting" is the importance of letting go of "what ifs" of medical testing and the "fear of the ramifications of the latest malady" discovered. Lots of praying. Lots of fellowship on the same side of the struggle as we groan with and for one-another. Casting for a fish is nothing compared to the need to cast our anxieties and worries for each other to the only One who can bring comfort. Jesus, who cares for each of us, His children!
Lately, as the cares of our hearts are many, His consolations cheer our souls. (Psalm 94:19)
So.....I keep prayerfully "casting" for dear friends.
