“For he shall be great in the sight of the Lord, and shall drink neither wine nor strong drink; and he shall be filled with the Holy Ghost, even from his mother’s womb.” (Luke 1:15)
This prophecy of the angel Gabriel, bearing as it does a tremendous testimony to the character of John the Baptist, contains the first reference in the New Testament to the unique Christian doctrine of the filling of the Holy Spirit.
It is significant that he was filled with the Holy Spirit all his life. Jesus is also said to have been full of the Holy Spirit (Luke 4:1) and was undoubtedly so filled from the time of conception (Psalm 22:10), but the explicit statement is made only of John.
The fullness of the Spirit is available for every believer, of course. In the New Testament, both of John’s parents were said to be so filled on a specific occasion (Luke 1:41, 67).
The disciples of the Lord were filled with the Spirit many times (Acts 2:4; 4:31; 13:52).
Barnabas was another Spirit-filled Christian believer (Acts 11:24). Undoubtedly there were many others. In fact, every believer is commanded to be “filled with the Spirit” (Ephesians 5:18). The reference in this key passage is not to a one-time event, but to frequent fillings. “Be continually being filled” is the literal rendering. HMM
