“Church membership is not intended to be a peripheral part of our lives. It is not intended to take up a few hours of our lives each week. That is very clear from the biblical teaching and that is what is reflected in the vowed for profession of faith and the explanation of them in our Form of Government. One verse that sums this all up is all up is 2 Corinthians 5:15 which says that Jesus “died for all that those who live might no longer live for themselves but for him who for their sake died and was raised.” The rest of the New Testament spells this out in considerable detail when it describes the life that is to flow from the saving grace of Jesus Christ through the Holy Spirit.”
