One of the most important ministries of the Holy Spirit is that of filling of the believer. The filling of the Spirit gives the believer power to live the Christian life. The believer is commanded to be filled with the Holy Spirit:

And do not be drunk with wine, in which is dissipation; but be filled with the Spirit (Ephesians 5:18).

 
The filling of the Holy Spirit is not something that is merely suggested by God; it is a command. All believers are to be filled with the Holy Spirit. The filling of the Holy Spirit is contrasted with drunkenness. The idea behind each concept is control. While the effects of alcohol control the drunken person the effects of the Holy Spirit control the believer. Thus, when we speak of being filled with the Holy Spirit, we are speaking of being controlled by the Holy Spirit.

The filling as contrasted with other ministries of the Spirit, is directly experienced. It is a repeated experience. The command in Ephesians 5:18 is for the believer to be continually filled with the Holy Spirit.
 
We conclude regarding the filling of the Holy Spirit:

1.  The Bible commands the believer to be filled with the Spirit.

2.  The idea behind it is control. God wants His people to be controlled by the Holy Spirit.

3.  The filling of the Holy Spirit is a ministry of the Spirit that is directly experienced by the believer.

4.  The filling of the Holy Spirit is a repeated experience.
