We are not worshipping if...

Since worship is focussing on and responding to God, regardless of what else we are doing we are not worshipping if we are not thinking about God. You may be listening to a sermon, but without thinking of how God’s truth applies to your life and affects your relationship with Him, you aren’t worshipping. You may be singing “Holy, holy, holy,” but if you aren’t thinking about God while singing it, you are not worshipping. You may be listening to someone pray, but if you aren’t thinking of God and praying with them, you aren’t worshipping” (Spiritual Disciplines for the Christian Life, pp.81-82).

How is it possible to worship God publicly once each week when we do not worship Him privately throughout the week? (Spiritual Disciplines for the Christian Life, pp.93).
