How was each Apostle Chosen?
Many people besides the four fishermen followed Jesus. His teachings were so new and carried such impact that many wanted to be his pupils or disciples. They followed his company from one place to another.
Finally its claimed Jesus felt he needed to choose twelve of these men for special training so they could help in his work. He wanted to send these men to places where he had never gone. They would preach to the people about the kingdom of God.
One night he slipped away quietly and climbed the mountain to pray. There in the quietness he prayed all night for help and wisdom and for strength to do his work.
When morning came Jesus was ready to choose his helpers. Leaving his place of prayer, he joined the company of followers who were waiting in the valley.
From them he chose Simon, whom he called Peter, and Andrew, the brother who first brought Simon to Jesus. Then he chose James and John, the brothers who had been partners with Simon and Andrew in the fishing business. Afterwards he chose Matthew, the publican; Philip, of Bethsaida; Thomas and Bartholomew; another James, who was the son of Alpheus; another Simon, also called Zelotes; Judas, the brother of James; and last of all Judas Iscariot, who finally sold his Lord for the 13 pieces of silver.
