Worship is the expression of the Christian believer’s relationship with God. However that relationship is very complex, since God is at one and the same time our Creator, Redeemer (through Jesus Christ), Sustainer, Indweller (by the Holy Spirit), Friend and Judge.
I helps to remember that we approach God individually as a created one, a redeemed one, a sustained one, an indwelt one, a befriended one, and a judged one.
