To worship God in spirit and in truth, then, is to declare that God is worthy of our reverence. We do this both through our emotional core and in light of reality. We worship God based on the truth of who He is, the truth of who we are, the truth of what God does, and the truth of what is going on in our world. We do it with a heart inclined toward God and in submission to Him. We worship God when our attitudes, actions, and words declare that He is worthy of our praise.
"Worthy is the Lamb who was slain, to receive power and wealth and wisdom and might and honor and glory and blessing!" (Revelation 5:12).
