Alternatively, always switching our prayer space from one place to another is too energy draining. We have to acclimatize our psyches to feelings generated by ever changing environs. Such fickleness might actually be a disguise for avoidance. Familiarity, on the other hand, can breed trust. We know that God has been with us in this place, and we can count on God to be with us again.
Repetition goes hand in hand with continuity.
If prayer is an evolving dialgoue between us and God, then we return not only to a familiar place, but also to a familiar story. Freed from the emotional chaos of constantly adapting to new environments, we can attend to the ever chaning story of our lives. In a familiar place, we pick up where we left off with God, so to speak, and our prayer becomes the unfolding of an ongoing life of transformation. Now, liturgy is such a familiar home to which we can return. Not only the physical structure of a church or chapel, but also the rites themselves, liturgy's gestures, words, music, smells, sounds, and tastes become a place where prayer happens.
