(12) Many say they have no peace nor rest, but so many crosses and trials, afflictions and sorrows, that they know not how they shall ever get through them. Now he who in truth will perceive and take note, perceiveth clearly, that true peace and rest lie not in outward things; for if it were so, the Evil Spirit also would have peace when things go according to his will, which is nowise the case; for the prophet declareth, “There is no peace, saith my God, to the wicked.”13 And therefore we must consider and see what is that peace which Christ left to His disciples at the last, when He said: “My peace I leave with you, My peace I give unto you.”14 We may perceive that in these words Christ did not mean a bodily and outward peace; for His beloved disciples, with all His friends and followers, have ever suffered, from the beginning, great affliction, persecution, nay, often martyrdom, as Christ Himself said: “In this world ye shall have tribulation.”15 But Christ meant that true, inward peace of the heart, which beginneth here, and endureth for ever hereafter. Therefore He said: “Not as the world giveth,” for the world is false, and deceiveth in her gifts.

(2) Jesus said unto his disciples: "Be comforted and be not afraid, for ye are blessed, because I will make you lords over all these and put them in subjection under your feet. Remember that I have already said unto you before I was crucified: 'I will give you the keys of the kingdom of heaven.' Now, therefore, I say unto you: I will give them unto you."

(12) She promiseth much, and performeth little. Moreover there liveth no man on earth who may always have rest and peace without troubles and crosses, with whom things always go according to his will; there is always something to be suffered here, turn which way you will. And as soon as you are quit of one assault, perhaps two come in its place. Wherefore yield thyself willingly to them, and seek only that true peace of the heart, which none can take away from thee, that thou mayest overcome all assaults. Thus then, Christ meant that inward peace which can break through all assaults and crosses of oppression, suffering, misery, humiliation and what more there may be of the like, so that a man may be joyful and patient therein, like the beloved disciples and followers of Christ. Now he who will in love give his whole diligence and might thereto, will verily come to know that true eternal peace which is God Himself, as far as it is possible to a creature; insomuch that what was bitter to him before, shall become sweet, and his heart shall remain unmoved under all changes, at all times, and after this life, he shall attain unto everlasting peace.
