"It is one thing to become a Christian. It is another thing entirely to become a Spirit-filled Christian. The tragedy is that so many are converted and so few Spirit filled. When this happens, a person misses the best God has to offer us on earth."
John Stott, Ephesians
We need the Spirit to fill us because...
1) These days are evil (Ephesians 5:15-17)
2) It is the Better Way (Ephesians 5:18)
3) It Produces Rich Responses (Ephesians 5:19-21)
