Prepare to Worship

In Burroughs book he stated the importance of preparing your heart for worship. He then mentioned the great amount of time that was lost in worship when we do not come prepared. Instead of coming before God ready to worship, we often go to God, and half-way through worship or prayer we are finally at a spot where our hearts are close enough to God's. I know atleast I am often guilty of this. It is sad to think of all the time I have wasted in both church and prayer because I did not properly prepare myself to come before God.
