Likewise the Spirit helps us in our weakness; for we do not know how to pray as we ought, but the Spirit himself intercedes for us with sighs [and expressions] too deep for words. -Rom 8:26
I like this Scripture verse because it is so accurate about our prayer life. Take any night of the week. It’s late. You’re tired. Hours of busy-work still stand between you and bedtime. At this hour you hardly remember the New Year’s prayer routine you resolved to keep a few weeks ago. Because of fatigue, frustration, or boredom, there may be literally no words to express how you can or ought to pray right now.
