We have been given the opportunity to gain our freedom through Jesus, it cannot be purchased through deeds, it cannot be won by showing up for church, it can only be gotten through faith. Faith without deeds is dead, conversely deeds without faith are also dead. Neither will get us anywhere.
We must then live according to Gods will in our lives, a living faith, one by which others will come to see Christ in us. We must exercise that faith by serving others, that is where we gain our freedom. In service to others, an unselfish service, we give back to God what he has given us.
