Paul was a zealous man, first trying to destroy the spread of Christianity, later serving Christ with an equal amount of zeal. His life changed after a personal encounter withe the living Christ. In 2 Corinthians 5 Paul reminds the Corinthians that when we embrace the truth that Christ died to pay the penalty for our sins, our old life dies. We are to now zealously live not for ourselves, but for our Redeemer. The love of Christ compels us to serve him with all that we are.
