They tell about a fifteen-year-old boy in an orphans' home who had an incurable stutter. One Sunday the minister was detained and the boy volunteered to say the prayer in his stead. He did it perfectly, too, without a single stutter. Later he explained, "I don't stutter when I talk to God. He loves me."
When prayer is a struggle, do not worry about the prayers that you cannot pray. You yourself are a prayer to God at that moment. All that is within you cries out to Him. And He hears all the pleas that your suffering soul and body are making to Him with groanings which cannot be uttered.
