(James 5:16 KJV)
The effectual fervent prayer of a righteous man availeth much.
When God designs to do some particular work in his Church he pours out on his followers the spirit of grace and supplication; and this he does sometimes when he is about to do some especial work for an individual. When such a power of prayer is granted, faith should be immediately called into exercise, that the blessing may be given: the spirit of prayer is the proof that the power of God is present to heal. Long prayers give no particular evidence of Divine inspiration.
