When we consider the New Testament epistles, where believers are given prescriptive instruction for church life, we find that being filled with the Spirit is demonstrated not through ecstatic experiences but through the manifestation of spiritual fruit. In other words, Spirit-filled Christians exhibit the fruit of the Spirit, which Paul identifies as “love, joy, peace, longsuffering, kindness, goodness, faithfulness, gentleness, self-control” (Gal. 5:22–23). They are “led by the Spirit” (Rom. 8:14), meaning their behavior is directed not by their fleshly desires, but by the sanctifying power of the Holy Spirit.
