If you think about it…being the Son of God, Jesus was exempt from the tax. But not wanting to be a stumbling block to the people of Capernaum, Jesus used it to be a faith-building opportunity for Simon Peter. Using Peter’s gift, his talent, his vocation of fishing, Jesus instructed him to go to the lake, cast out his line, and pull in the first fish he hooked. He then told Peter to open its mouth and inside he’d find a four-drachma coin to pay the tax for both of them. By just being obedient with the skills he already had, Peter’s faith was increased greatly, and he was blessed over and above what he could imagined.
