Preparation: At Home or in Church?

Burroughs discusses in detail the vital importance of the preparation of the soul before worship. He also notes how one should still go through with the duty even if there has been a lack of preparation on the part of the person (pp. 70-74). My question deals with this point of preparation: In light of the "busy-ness" of this culture, does the church need to supply a time before the worship service begins for its people to quiet their hearts before God? In other words, does this preparation need to take place in the home or in the church? Obviously, in the ideal world, we would hope that everyone would always have his or her soul ready for worship or at least have the time and desire to prepare oneself before going to church, but practically it is not always possible (e.g. mothers getting ready their children).
