for the Essentials Blue In Worship Theology Course with Dan Wilt
What is worship? Is it music? Is it dance? Is it songs? When we say "let's worship" we typically mean something to do with music, but worship, in it's most truest form is so much more than that.
Worship is expression, prayer, compassion, proclamation. It is practiced within our relationships with family, friends, strangers, our culture. It requires character growth and holiness and a pursuit of truth. It resists compartments and embraces wholeness at every level. Worship invades every aspect of our lives and reveals who it is we are focusing on because we become like what (or who) we worship. 
As a Christian, I worship God. And I can only worship Him as He chooses to reveal Himself to me. He loves me, and I get to love Him back, pulling from the love He deposited within me. Worship belongs to Him and I can only do it out of what He has given me.
It's not a show to impress Him, to let Him see how hard I can work. It's a healing, restoring, beautifying experience that He initiates and I respond to. It's my whole life living in response to His love for me. 
N.T. Wright says that it is the task of humans to relect God into the world like an angled mirror.  Then I get to reflect back to God the "inarticulate praise" of the inanimate creation by articulating it through prayer, song, dance, art, words...
Matt Redman says that the revelation of God is what fuels the fire of worship. Without revelation there is no worship.  It is my responsibility to press into God and to watch for Him to reveal Himself to me. I must determine to keep my eyes fixed on Him so as not to miss the revelation, particularly in challenging circumstances when the temptation is to turn my eyes to the challenge and try to figure out a way to work things out. Worship means keeping my eyes fixed on Him, the Author and Perfecter of my faith, and trusting Him to strengthen and deepen my faith, praising Him and declaring His eternal attributes of faithfulness and goodness, knowing that He will work all things together for my good and that He will lead and guide me in the way I should go.
As I purpose to do this day in and day out, intimacy with God grows more intimate. Relationship with Him is the real adventure of worship and is never boring or dull. Brian Doerksen says, "Real intimacy is real adventure." Amen.
This intimacy allows me to have a life formed by Jesus that is at peace whether He is speaking or is silent. It allows me to be confident in the light or in the darkness because regardless of how it feels, I know that He is with me, actively loving me. It enables me to carry His image into the world and to show compassion in practical ways that change culture, establish justice, redeem brokenness, and free captives. Intimacy is the fount from which worship in spirit and in truth flows from me to the Father, Son and Spirit, relecting His image to the world around me.
