Mark 1:17 Then Jesus said to them, “Follow Me, and I will make you become fishers of men.”
How good were Simon and Andrew at fishing? Well they must have had some success because they were known as fishermen!
They must have thought themselves to be good enough to make a living from the fishing as well.
What made them stop and follow Christ? It was what Jesus was saying. It was the gospel.
Don’t take my word for it; stop and read the first chapter of Mark and see what Jesus was doing; it may just open your eyes too!
