Chapter XIII.

That we should not retain our anger even for an instant.

how can we think that the Lord would have it retained even for an instant, since He does not permit us to offer the spiritual sacrifices of our prayers, if we are aware that another has any bitterness against us: saying, &#8220;If then thou bringest thy gift to the altar and there rememberest that thy brother hath aught against thee, leave there thy gift at the altar and go thy way; first be reconciled to thy brother, and then come and offer thy gift.&#8221; How then may we retain displeasure against our brother, I will not say for several days, but even till the going down of the sun, if we are not allowed to offer our prayers to God while he has anything against us? And yet we are commanded by the Apostle: &#8220;Pray without ceasing;&#8221; and &#8220;in every place lifting up holy hands without wrath and disputing.&#8221; It remains then either that we never pray at all, retaining this poison in our hearts, and become guilty in regard of this apostolic or evangelic charge, in which we are bidden to pray everywhere and without ceasing; or else if, deceiving ourselves, we venture to pour forth our prayers, contrary to His command, we must know that we are offering to God no prayer, but an obstinate temper with a rebellious spirit.
