Prayer is a condition of mind, an attitude of heart, which God recognizes as prayer whether it manifests itself in quiet thinking, in sighing or in audible words.
Ole HallesbyWithout faith there can be no prayer, no matter how great our helplessness may be. Helplessness united with faith produces prayer.
Ole HallesbyWhen 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.
