A popular Christian worship song boasts "I'll become even more undignified than this" in reference to how David wildly danced before the Lord in adoration.
All, who worship in accord, express a desire to worship God in more of an abandoned way than even David, who forsook his own pride and dignity. The lyrics acclaimed are a commitment to let go of one's own inhibitions and perservations, in order to move into extravagant worship --expressing passion and love for God. Committing to exceed David's exhibition of passion is a big aspiration, because David was the ONLY one throughout Scripture that God, Himself, coined as  "A Man after My Own Heart."

Of course, not all venues and occasions are appropriate for dance or elaborate physical expression --
but such reckless abandonment is never appropriate for many who are more concerned about dignity and propriety.

Regardless of individual's nature,  personality types and preferences-- the God of Glory deserves uninhibited worship of our entire beings--for glorifying Him is  the very reason that we are created.

Though the enemy has usurped dance for secular venues and acquainted it with mere entertainment, true dance is for the Lord because it's an optimized expression of joy and gladness. He is the God who fills His people with joy and sets our feet ablaze. 
God doesn't want our passion and zeal for Him to be snuffed out due to traditional composure.
Jesus rebuked those who sought the honor of men, esteeming it more than the honor of God (John 5:43-45). And He even insists that we exhibit the humility of little children in order to enter into the kingdom of heaven (Matt. 18:2-4).

When David brought the ark of God up to Zion, the dwelling place of the Lord was no longer aloof from Israel, separated behind a veil, but His abiding Presence was in their MIDST and they jubilantly worshipped day and night. The same Holy Spirit that empowered Israel to win battles, dwell safely, and possess abundance is still giving His people Victory today! In the Old Testament we read how Amos prophesied of a future day when God would restore the Tabernacle of David --because He still desires to be in the MIDST of His People and receive the glory that's due His Name.
Today we are seeing this restoration fulfilled because, through Christ, the same glorious Holy Spirit is abiding in His people.
And the more God's people surrender to a greater aspiration of worship, the more room God has in hearts to manifest Himself.
Consequently, the more God shows up in our midst --- and that's something to get excited about!! 
That's all the more reason to release our hearts and souls into full expression of worship.
And that's all the more reason to-----------DANCE!
