When we gather together we encounter Christ in one another, meeting the Lord and engaging Him in worship. Our work of worship must be seen as spiritual worship described in Romans 12: 1 and 2, which embraces the whole of life.
We should not gather for worship as a means to an end - such as preparation for worship and witness in everyday life. It should be about the wider worship of the congregation continuously repeating and rehearsing total self-surrender as a believer in our daily walk, our lives. When we minister to one another in love in the Body, we are seeing the Spirit's transforming power at work - demonstrated right in front of us, which is an important way of worshipping and glorifying God. The unbeliever in our midst actually potentially sees this also.
We should never separate the vertical and the horizontal in our worship when the church gathers. We don't look at prayer and singing praise as the worship time and the teaching-preaching as the edification time. Paul's teaching encourages us to view all activities as both vertical and horizontal. Ultimately, it all is for the glory of God! mjm
