Jesus miraculously fed thousands of people on two occasions because of availability. On each occasion, everyone was in dire straights, but Jesus came through with a miracle of plentiful provision based on the simple principle of using what was available. Jesus used a meager few fish & loaves of bread, the provision that they had, along with His disciples as distribution agents. I would speculate that maybe one or two of the disciples thought it was crazy to be sent to feed thousands of people with such a paltry provision & yet because they were available, Jesus worked His miraculous provision through their available hands & feet. Jesus prayed for the provision & then told His disciples to go & give.
Seems to me that the same principles apply to us today. Jesus merely asks us to be available & then to go & give.
