Too much to blog about!

"Quicken your heart and rouse up your spirit when you are to worhsip God." (pp. 137-138) Burroughs states this when he is talking about how we should not come to worship in our own strengths but to rely on God to grant us strength to worship Him. He also mentions that when worship we must stir up within ourselves the strength that God has given to us to do so. My question is, what exactly does Burroughs mean by this? Does that mean praying before you come to worship or setting your mind on things of God to prepare yourself for worship? I believe Burroughs mentioned this earlier in the book as well, possibly in his ideas on preparation. What are practical examples of "quickening your heart and rousing up your spirit"?
