There are serious limitations to spiritual disciplines. Engaging God via spiritual practices (memory recollection activities) assumes that God resides in the mind; that we only connected with him when we remember him, and therefore we need activities that produce remembrance. This denies the fact that God resides with our spirit, not our mind. Practicing the presence of God comes from dividing soul and spirit.
Activity based presence will never maintain presence because we cannot maintain activity. We can up the frequency of activities, but never sustain them. The answer is to reside in the presence of God via spirit regardless of our activities. When this is in place, prayer retreats and washing your floor therefore become equally spiritual. According to Watchman Nee, “No matter how noisy it is outside, the inside does not need to respond.” Deal with outside stuff on the outside, leaving your spirit unaffected within the presence of God.
