The answer
The New Testament Church inherited worship through praise from the temple in Jerusalem where there were groups of people whose role it was to offer praises. It is said that the number of harps there was more than four thousand. The Church, the daughter of Zion, imitates David the king and the prophet, the sweet psalmist of Israel (2 Sam. 23:1) and finds joyful depths in the psalms, in the light of the work of Christ — the son of David — on the Cross, in His resurrection, and in His ascension to heaven. The apostle Paul knew the kingdom of God as joy in the Lord (Rom. 14:17).
