Worship is the "response of God's redeemed people to His self-revelation that exalts God's glory in Christ in our minds, in our affections, in our wills—and all that is in the power of the Holy Spirit. It takes God to worship God." (Bob Kauflin interview during InDoubt.ca Podcast)

In response to reflecting on God’s self-revelation (of His nature/attributes, works and will), we (God’s people, by His Spirit), exalt (worth-ship) Him to the best of our abilities (with our mind & attitude, affections, will, words and works), showing reverence (we RESPECT Him), awe (we are AMAZED at Him) and servanthood/devotion (we SERVE Him).

There are many areas besides preaching and leading worship. See below where you could participate in leading others (INCLUDING in preaching and leading worship!)
