Christianity is a spirital change into living in spirituality.  This becomes the beginning of salvation.  Jesus said "if God were your father you would love me," (John 8:42).  There is only freedom in spirituality to live in the truth of God the Father.  "For us there is only but one God the Father, from whom all things come from, and for whom we live and there is but one Lord Jesus Christ through whom all things come and through whom we live," (1 Corinthians 8:6).
