1.  Believers are commanded to be filled with the Spirit (i.e. to willingly place themselves under the control of the Holy Spirit).  Ephesians 5:18

2.  The issue is not how much of the Holy Spirit do we have (we will never have more of the Holy Spirit than we do at the moment of salvation).  The issue is how much of us does the Holy Spirit have?

3.  The conditions for being filled with the Spirit are:  we must deal with sin in our lives (Ephesians 4:30); we must acknowledge God’s right to our lives and consciously yield to God (Romans 12:1; 6:13; Galatians 2:20); and we must live a life of dependence allowing the Spirit to have full control (Galatians 5:16).

4.  The results of and evidences of being filled with the Spirit are: Christlike character (Galatians 5:22,23); worship, praise and thanksgiving (Ephesians 5:19,20); and right relationships in marriage, the home, on the job and in the church (Ephesians 5:21ff).
