"To claim the Holy Spirit can use baptismal water is apparently superstition, but the use of Bibles and sermons is not - even though material means are equally involved in both.
When the Spirit anoints something, that makes it effectual, and the effect is immediate. The Spirit's work does not come through the means (the sermon, the sacrament) like water through a garden hose. Rather, the Spirit's anointing is given on account of the means...But if we show up later with our tiny cages in order to capture those very same means, hoping to chain the Spirit up, we find that He is gone." - Wilson, AC, p 193.
