Worship is not the slow song that the choir sings. Worship is not the amount you place in the offering basket. Worship is not volunteering in children's church. Yes, these may be acts or expressions of worship, but they do not define what true worship really is. There are numerous definitions of the word worship. Yet, one in particular encapsulates the priority we should give to worship as a spiritual discipline: Worship is to honor with extravagant love and extreme submission (Webster's Dictionary,1828).
True worship, in other words, is defined by the priority we place on who God is in our lives and where God is on our list of priorities. True worship is a matter of the heart expressed through a lifestyle of holiness. Thus, if your lifestyle does not express the beauty of holiness through an extravagant or exaggerated love for God, and you do not live in extreme or excessive submission to God, then I invite you to make worship a non-negotiable priority in your life.
