Proper worship is characterized by both order and joy

1 Chronicles 16:1-6
They brought the ark of God and set it inside the tent that David had pitched for it, and they presented burnt offerings and fellowship offerings before God. After David had finished sacrificing the burnt offerings and fellowship offerings, he blessed the people in the name of the Lord. Then he gave a loaf of bread, a cake of dates and a cake of raisins to each Israelite man and woman.
He appointed some of the Levites to minister before the ark of the Lord, to extol, thank, and praise the Lord, the God of Israel. 
They were to play the lyres and harps, Asaph was to sound the cymbals, and Benaiah and Jahaziel the priests were to blow the trumpets regularly before the ark of the covenant of God.
Proper worship is characterized by both order and joy. From earliest times music has held a special place in worship.
Why?
Worship need with joy and order. So music is necessary, and David assigned special men to this mission.
After burnt offering to the Lord, David blessed people of Israelites and he gave bread, cake to each Israelite man and woman. Here shows his mercy with action, and treated man and woman equal.

敬拜代表人對神完全奉獻。燔祭：完全燒掉，神完全接納人，神與人關係密切
平安祭： 慶祝神人關係好的祭，神賞賜豐盛的宴席。所以每個參加的人都可以領受神的恩典。當時百姓收到這些，肉不是當時一般人常吃的到的。
約櫃進入帳幕後，音樂持續在進行中。詩班、樂團是每天都在進行的。無論情緒、天氣、都要讚美神。神的名得榮耀，人就可以得著平安。
燔祭、平安祭固然是馨香之祭，但是出於心靈、誠實的讚美、感恩的敬拜更是得神的喜悅，超過任何的禮物。如兒女與父母談心、說話甚於贈送禮物，討父母喜悅。
