Peter and the others were exhausted -- and disappointed. They'd worked hard all night without success. Now they were on shore, washing their nets and getting ready to head for home empty handed for all their labor.
Then Jesus comes along and tells them to push out again into the water and let down their nets.
And that's when St. Peter says something I hope to never forget -- and to always put into practice, regardless how tired or discouraged I might be:
Master, we worked hard all night and caught nothing, but at your bidding I will let down the nets (Luke 5:5).
My responsibility is not to assess the outcome of my work for His kingdom -- even if my work looks useless. My responsibility is to simply do what He tells me to do -- again and again -- even if I don't see the value in it.
But at Your bidding I will let down the nets.
