While walking by the Sea of Galilee, he [Jesus] saw two brothers, Simon (who is called Peter) and Andrew his brother, casting a net into the sea, for they were fishermen. And he said to them, “Follow me, and I will make you fishers of men.” (Matthew 4:18-19 ESV)
Starting with Peter and Andrew, Jesus selected a group of ordinary men, in mundane trades and occupations, to be his 12 disciples (students). He knew their faults before choosing them, but He specifically chose and trained them. He taught them the Scriptures, how to pray, how to forgive, and how to serve others with humility.
In teaching them, Jesus was preparing them to be His instruments. With the exception of Judas who He knew would betray Him, the disciples later as apostles (messengers) started the church and the work that continues today, 2,000 years later, to accomplish His sovereign will.
As ordinary men before Christ selected them, they are vivid proof that God’s strength is made perfect in weakness (2 Corinthians 12:9). They were instruments in His hands, just as we can be God’s instruments in His hands today. What do you hear God calling you to do?
"You become stronger only when you become weaker.
When you surrender your will to God,
you discover the resources to do what God requires."
