What is Worship?
Beholding the One who is most lovely.
Worship, as a spiritual discipline, is the intentional practice of recognizing who God truly is and responding to him with reverence, love, trust, and obedience. It is also about who God is and who you are in relation to Him. It is not primarily a music style, or a Sunday morning experience, or an emotional state you try to manufacture. Those things can certainly serve worship, but they are not worship in and of itself.
Dallas Willard defines it simply as "acknowledging the greatness and beauty of God." Richard Foster puts it similarly but adds an important aspect. He calls worship, "the human response to the divine initiative." Meaning God moves first. Always. Put this way, worship as a spiritual discipline is our answer to what He’s already done. It is the foundation in which every other discipline begins.
We become what we worship. The Psalms are built on this idea; Paul articulates it in 2 Corinthians 3:18…We are being transformed into the image of whatever we fix our gaze on. The reality is, everyday we point our worship at something or someone. We are often unaware that it is happening, but it is. Everyone is worshiping something. So the question is whether what you're orienting your life around is actually worth your worship. Worship, as a spiritual discipline, is to remind yourself of this truth and reorient your worship to the only one who is actually worthy of it. Every human heart ultimately orients itself around someone or something that becomes its highest love, trust, or allegiance. Every time we deliberately turn our attention and worship toward God, we are training ourselves to see correctly. Worship does something to us that nothing else can, it reorders our loves. Not through willpower or behavior modification, but through encounter. Whenever we genuinely behold God's holiness and love, the Spirit is at work transforming us, even when the change is slower than we can see.
