When you have peace and love for all, then your prayer is acceptable

Rightly did the Lord say, ‘My burden is light’. For what sort of weight is it, what sort of toil is it to forgive one’s brother his offences, which are light and of no importance, and to be pardoned for one’s own, and immediately justified?

He did not say, ‘Bring me money, or calves, or goats, or fasting, or vigils’, so that you could say, ‘I have none, I cannot’, but he ordered you to bring what is light and easy and immediate, saying, ‘Pardon your brother his offences, and I will pardon yours. You pardon small faults, a few halfpennies, or three pennies, while I give you the ten thousand talents. You only pardon without giving anything, I nevertheless both grant you pardon and give you healing and the Kingdom.

And I accept your gift, when you are reconciled to the one who is your enemy, when you have enmity against no one, when the sun does not go down on your anger.

When you have peace and love for all, then your prayer is acceptable, and your offering well-pleasing, and your house blessed and you blessed. But if you are not reconciled with your brother, how can you seek pardon from me? You trample on my words, and do you demand pardon? I, your Master, demand, and you pay no attention, and do you, a slave, dare to offer me prayer, or sacrifice, or first fruits, while you have enmity against someone? Just as you turn your face from your brother, so I too turn my eyes from your gift and your prayer.’

St Ephrem the Syrian
