Scripture in Matthew 4 and Mark 1 tells of Jesus calling fishermen to be His disciples, but only Luke 5 tells the story of how He made for them provision in advance of their commitment. This is my personal view of the story:
Being told to push out into the deep to catch fish, Simon said, "Master, we've been fishing hard all night and haven't caught even a minnow. But if you say so, I'll let out the nets." Immediately there was a huge haul of fish, straining the capacity of the nets. They called to their partners to come help them to help bring in the catch and share in the provision. The catch was sufficient to meet their needs and sustain their families. So, they left their boats and became fishers of men.
Now we enter the 7th Day, which is a time of fullness for the Kingdom on earth. And as with the fishermen, it begins with provision for the called. From the deep riches of Babylon and the storehouse of gold in Asia we are called to reap a Jubilee - more than enough to be debt free and have provison for every good work.
