Jesus freely exchanged His life for ours, so we might give ours to God, and so come home to true life. This is called repentance. God confirms our new relationship with Him in baptism [or simple profession of faith]. In this we affirm that we will live a new life in Jesus, and enter into God’s family, the Church. So you can see that becoming a Christian is not matter of doing your own faith thing, nor is it ‘going to church’ for Sunday worship. Rather it is committing your life to walk in the way of Christ Jesus, in the family of the Church, and the lively power of the Holy Spirit, to the gory of God the Father. It means belonging to a people living God’s way in and by sharing Jesus in Word and Action.
