The worship in this text has its basis in God's deliverance of His people from end-time Babylon (Rev. 19:1, 2). In Revelation 4 and 5 worship takes place in response to creation and the cross, just as in the Old Testament, worship responded to God's mighty action in Exodus. True worship is always about an awareness of the mighty things that the Lord has done for you. And the result of true worship is tangible. When we remember and recite what He has accomplished, it rekindles His mighty power in us and changes our lives.
One Old Testament passage especially unpacks this in detail: 2 Chronicles 20:1-23. The Israelites are under attack, outnumbered three to one. The enemy army has advanced to less than 30 miles from Jerusalem. King Jehoshaphat proclaims a fast and goes to the Temple courts to lead the prayers.
Now, if you were in his shoes, what would you pray about? "O Lord, help us! Do something please! We're in big trouble!" Prayers get real focused when you are about to die. But Jehoshaphat's actual prayer doesn't sound desperate at all. Instead of whining and begging, he just recounts God's actions in the past. He reminds God of the Exodus and how He had promised the land to the Israelites forever (2 Chron. 20:6-9). Then the king puts God on the spot. "These nations wouldn't even exist if You hadn't spared them at the time of the Exodus!" (see verses 10-12). Through a prophet God assures him not to worry about the battle. The Lord will fight for them.
So what does Jehoshaphat do next? He sends out the Temple choir to lead the army into battle (verses 22, 23). And the enemy perishes. What did the choir sing that day? It wasn't "Trust and Obey"! Rather, they sang, "Give Thanks to the Lord, for His Love Endures Forever." Focused on God, not on the problem, they were rehearsing His mighty acts.
And what happened when they did that? It reignignited the power of the original act in their midst. The power of the Exodus became a living presence among them. And the result was another mighty act of God to celebrate in the future!
Lord, I'm grateful for all that You have done for me in Christ. I desire to experience His resurrection power in my life today.
