Worship in the Spirit requires control by the Spirit. When Paul forbids the filling that comes from wine (Ephesians 5:18), it is immediately contrasted by filling with the Spirit. The end result is control either way, but the difference is the means. Spirit filling is manifest in fruit bearing as opposed to debauchery. The better your walk, the more fruitful you will be. It is interesting to note that the spiritual person may look similar to the legalist. Observation may conclude both are outwardly righteousness. Self-control for example is common among religious people, but it doesn’t come from the Spirit. Fear or reward is adequate to induce compliance. The difference is when the Holy Spirit is at work he produces real fruit, takes joy in it, and receives glory from it. Patterns of true moral behavior are rooted in a biblical doctrine. Grace and piety are not mutually exclusive, and there is no need for errors on either extreme. Spirituality results from spiritual disciplines. Spiritual disciplines produce spiritual strength. The result is bearing spiritual fruit. This protects Christians from imposing preferences (true grace) or taking credit for godliness (true piety).
