“The apostle Paul uses a strange comparison and contrast to describe this work of the Spirit. “Be not drunk with wine, but be filled with the Spirit,” he admonishes (Eph. 5:18). So what happens when a person gets drunk? Well, the alcohol of the “spirits” gets into his bloodstream and permeates every part of his person. He walks differently and talks differently, and he sees, hears, and acts differently.
So is the experience of everyone who is “filled” with the Spirit. God’s holiness, the holiness of the Holy Spirit, permeates every part of his person. He goes happily to places of worship, praise, and prayer — places he would not otherwise go. He talks boldly about Jesus the Christ. To abuse, he responds with love.
This experience of being filled with the Spirit is not something that happens once and then is done. The phrase literally reads, “Be being filled with the Spirit.” Constantly, continually, more and more extensively, be permeated in all you think, say, and do by the abiding influence of the divine Spirit. It’s the greatest possible experience of life.”
