Another way of saying . . . "Making His Praise Known". We were chosen to . . . "declare the praises of Him who called us out of darkness into His wonderful life." Throughout the whole of Bible HIStory from eternity past until the new heaven and the new earth . . . God "seeks" worshippers. But the metaphor of seeking is very appropriate as we see how much trouble God went to, to plan the sacrifice of His own Son to redeem us for the purpose of worshipping Him.
Worship is not only one segment or part of the Christian life. Worship is the entirety of the Christian life. It is seen as a priestly offering to God. When we gather together as the church our time of worship is not just something as preliminary to something else. The whole point of our existence as the body is worship.
In Ephesians 1:1-14 Paul gives an awesome vision of God's sovereign purpose. It began before the beginning of time as God "chose us in Christ before the creation of the world" (v. 4). And then God "predestined us to be adopted as the sons of God" (v. 5), "redeemed us through the blood of Christ", (v. 7), and "revealed to us the mysteries of His will, which will be fulfilled at the end of history" (vv. 9-10). The climax of it all is the goal toward which all history moves - "the praise of His glory" (v. 14). Worship is the goal of the human life - "declaring His praises!" mjm
