Is there some part of your life which you are refusing to surrender at his behest, some sinful passion, maybe, or some animosity, some hope, perhaps your ambition or your reason? If so, you must not be surprised that you have not received the Holy Spirit, that prayer is difficult, or that your request for faith remains unanswered. Go rather and be reconciled with your brother, renounce the sin which holds you fast—and then you will recover your faith!
