The enemy of our salvation especially strives to draw our heart and mind away from God when we are about to serve Him, and endeavors to adulterously attach our heart to something irrelevant. Be always, every moment, with God, especially when you pray to Him. If you are inconstant, you will fall away from life, and will cast yourself into sorrow and straitness.
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.
