" To be “in the Spirit” (which in Pauline language is the same as to be “in Christ”), to “have” the Spirit, to “live by the Spirit” and to be “led by the Spirit”—these are all descriptions of every Christian believer, however young in the faith he or she may be, indeed from the very moment of his or her new birth (Rom 8:9, 14; Gal 5:25). "
