Acts 1:8 NIV
Being Spirit-filled is not limited to one particular brand of Christianity. Spirit filled people are found in every church and denomination. They are people who understand the need for the power of the Holy Ghost within them so they won't live a weak, defeated life.
The Word says to "ever be filled and stimulated with the [Holy] Spirit" (Ephesians 5:18), indicating that being Spirit-filled is something to which we submit ourselves. Ask God to fill you to overflowing with His Spirit so that everything you do today will be done through His power.
