On Preserving Peace Within Our Soul
The Grace of God in the coenobium primarily withdraws because we have not learned to love our brother according to the Lord’s commandment. If a brother affronts you, and at that moment you accept thoughts of anger and hatred against him, then you will feel that Grace has left you and your peace has been lost. For the sake of peace of soul, the soul should learn to love the person that has affronted it, and to pray immediately for him. It is not possible for the soul to have peace, if it does not ask the Lord with all its strength for the gift of loving all people. The Lord said: “Love your enemies,” and if we do not love our enemies, we will not have peace in our souls.
