If you wish that God should speedily give you hearty faith in prayer, strive with all your heart to speak and to do everything in regard to other people sincerely, and never be deceitful in your dealings with them. If you are straightforward and truthful with others, then God will give you straightforwardness and sincere faith also in reference to Himself.
Each Christian, especially a priest, should follow in example the goodness of the Lord, that everyone should be invited to partake of the Lord's food at your table. The miser is an enemy of the Lord.
