I don't always keep up with my daily spiritual disciplines. What I have learned over the years is that I seem to need variety. I can't always do the same routine day after day. This doesn't mean that I don't try to maintain a spiritual discipline routine. But I can't keep it up for a long period of time before I need a change of some kind.
The problem is that during that change mode I am tempted to abandon or lessen my daily routine. For the moment there is a freedom that comes with changing my rule of life. But as with any void something will get sucked into that space...people, things, ideas. And God gets squeezed out.
The reason why maintaining spiritual disciplines is a good thing is that they mystically place me in the best possible position to listen to the voice of God and receive the grace of God. I think of the times when I am not centered and in a moment of distraction, temptation, or willfulness, I miss a beautiful God moment.
It is entirely possible that the God moment awaiting us tomorrow may be linked to our decision to place ourselves in a prayerful position today.
