David De Bruyn has been publishing “A Worship Catechism” at Churches Without Chests. It is well worth a look. I’ve linked to the first installment, but there are several.
1. What is the great priority and purpose of man?
Man’s great priority and purpose is to love God with his entire being: heart, soul, mind and strength (Mk 12:29-30).
2. Why is this man’s great priority and purpose?
Loving with the entire being is worship: expressing the worth and value due to God (Ps 29:1-2). Man was created to express this glory (Is 43:3), as image-bearers (Gen 1:26-27), just as the entire created order is to reflect and magnify the worth of God (Psa 150, Rev 4:11).
3. Why should all creatures magnify God’s worth?
God is Beauty (Job 40:9-10). The Triune God is the perfection of all excellence in Being, the most delightful conjunction of all attributes of Deity, the quintessence of truth and goodness, and the most admirable and sweetest expression of this loveliness. This glory calls for the appropriate response of highest enjoyment and admiration (Psa 113:3).
4. Why should God delight in this worship?
God delights in His own glory above all things, knowing that the magnification of His glory is the greater good of all (Joh 17:24-26)
