Paul's command for the entire Christian life. Galatians 5:16: This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh. The Greek peripateite pneumati is present-tense imperative — continuous, daily, settled walking. Romans 8:1-4 develops the same theme: those who walk after the Spirit have the righteousness of the law fulfilled in them. Walking is the biblical metaphor for the whole pattern of life — not occasional spiritual moments but the steady habituated direction of the daily course. The Spirit is not merely consulted in emergencies; He is walked-in. The result is two-fold: the works of the flesh are not fulfilled (Gal 5:16) and the fruit of the Spirit grows (Gal 5:22-23). The walk is enabled by the indwelling Spirit but is also the believer's active responsibility — the synergy of divine power and human walking that characterizes the entire Christian life.
