Mark 1:16-17
As He (Jesus) was going along by the Sea of Galilee, He saw Simon and Andrew, the brother of Simon, casting a net in the sea; for they were fishermen. And Jesus said to them, "Follow Me, and I will make you become fishers of men."

Scripture has always called for fathers to train up their children in the way they should go—and still does. {Prov.22:6} While that is surely focused on the spiritual things, it was and still is very common in many cultures around the globe for fathers to train their sons with the natural skills to carry on the family business.

Jesus, the carpenter {Mat.13.55}, would have been trained by His father Joseph to carry on the family business, to build and to repair things primarily of wood in his shop which was the custom of that place and time. Of course, His heavenly Father called Jesus to re-pair all of mankind to Him on the wood of the cross!
 
In today's verse Jesus now calls two fishermen, Peter (Simon) and Andrew to use their lives to reconnect others to God, to become fishers of men!
 
A thousand years before that, there was a young man from Bethlehem named David who was a shepherd and who faithfully cared for his father Jesse's flock. {1Sa.17:34-36} His heavenly Father then called him to shepherd His own flock as the King of Israel. That is David who said that all of his days were ordained 'when as yet there was not one of them.' {Ps.139:16}

Jeremiah, the son of Hilkiah the priest, was the prophet who the Lord said He knew and appointed to his ministry even from before the day he was born. {Jer.1:5} That ministry was one of bringing the Lord’s word to His people, regardless of how those people were willing—or not—to receive it!

Now, knowing that the Lord is no respecter of persons {Act.10:34,Rom.2:11} and that the truth of the Word applies to us, we know that He has a plan for you and I my brother and sister. And that is a plan that was formed before our flesh was! As it is written He made everything, including us, for His purpose. {Pr.16:4} And of course He reveals His purpose: “The people whom I formed for Myself will declare My praise.” {Is.43:21}

The apostle Paul wrote that we don't know how to pray as we should {Rom.8:26} so perhaps we should consider spending more time seeking the Lord, asking to better see, understand, and fulfill the ministry in our life that He has purposed to serve Him. A far better way to live as opposed to seeking what He can do to serve us! We need to have, and are called to have, the mind of Christ:
 
“Therefore Jesus answered and was saying to them, Truly, truly, I say to you, the Son can do nothing of Himself, unless it is something He sees the Father doing; for whatever the Father does, these things the Son also does in like manner.” (John 5:19)
