Jesus chose ordinary fishermen as disciples & they quickly saw that with Him they took in great hauls of fish. But He called them to be fishers of men & when they threw out the Gospel net, they brought in great hauls of souls.

But big game fish must be caught with hook & the right bait. It fights very hard & the fisherman has to give it enough line but hold onto the rod till the fish tires & gives up. It's the same with many unsaved who put up a huge fight, but if we will not let go of the rod, the Word of God, give them some line, they will eventually come in.
