It came to pass that the people pressed upon him to hear the word of God. He entered into one of the ships to go out a little from the land. After he finished speaking, He said to the ship owner... "launch out into the deep and let down your nets for a catch."
Friends, my question to you... are you willing to go out into the deep? Is not Jesus with you in your vessel? Yes, you are tired from fruitless and failed efforts of your labors just as Simon failed at catching nothing from all night of fishing.
Simon was missing his key component, he did not have Jesus in the vessel the evening of all night fishing that resulted in nothing. We need Christ in our labors because it will be of vain efforts if He is not with us.
Launch out with Christ and cast your nets in faith. His grace will more than supply. Be willing, obedient and exercise faith in Him for the harvest.
