Don't tell me that you have a Reformed Church in the tradition of Calvin until you have the preaching of the Word every day of the week, devote Wednesday's to prayer and have the church gather together for prayer.
It is God who gives us the spirit of worship (Psalm 133:3), and it is what we know of God that produces this spirit of worship. We might say that worship is simply theology, doctrine, what we think about God, going into top gear! Instead of merely thinking about Him, we tell Him, in prayer and praise and song, how great and glorious we believe Him to be!
You do not become a master musician by playing just as you please, by imagining that learning the scales is sheer legalism and bondage! No, true freedom in any area of life is the consequence of regular discipline. It is no less true of the life of prayer.
