Launch Out Into the Deep?

My devotion today centered on Jesus' saying to Peter in Luke 5. Why did Jesus say to Peter, "Launch out into the deep?" I believe it's because it's in the deep waters where you find the big fishes! Most people prefer the shallow waters of life. It's safer there. More comfortable. Piddle around. Just stay back, don't rock the boat. The result is existence on a superficial level. I've been learning that when God works, He always aks me to take risks. Get out into the deep water. Face the waves. From a human point of view, it appears ridiculous. But I don't want to live in the shallows of life. I don't want to miss out on so much of God's plan. More of His presence is in the deep waters, not in the shallows.
