Galatians 5:25

If we live in the Spirit
Or "by the Spirit", as all do that are spiritually alive. Sin has not only brought on men a corporeal death, and made them liable to an eternal one, but has also induced upon them a spiritual or moral death; they are dead in trespasses and sin, nor can they quicken themselves, nor can any creature give them life; not the ministers of the word, nor the angels in heaven, only the blessed Spirit is the spirit of life from Christ; who entering into them, frees them from the law of sin and death, and implants a principle of spiritual life in them, whereby they live a life of faith on Christ, of holiness from him, and communion with him: and this the apostle makes use of, as an argument with believers to walk after the Spirit,

let us also walk in the Spirit:
or "by the Spirit"; by his help and assistance, according to the rule of his word, and under his influence and direction as a guide, to which he had before advised in ( Galatians 5:18 ) .
