From the Word
Peace I leave with you; my peace I give to you; not as the world gives do I give to you. Let not your hearts be troubled, neither let them be afraid.
John 14:27, RSV
This is bidding them a friendly good-night. Christ was willing and able to speak with his disciples in the most loving manner. I must away, he says, and cannot speak much more with you; let it be well with you. That is my last farewell. Ye shall suffer no hurt, nor want because of my departure. I will richly repay you, for ye shall have from me the best that you can wish, namely, that in my Father you have a merciful God, whose thoughts toward you are those of a father’s heart and love. In me you shall have a good, faithful Saviour, who will not forsake you in any need and will defend you against the devil, the world, and all wickedness, and will in addition send you the Holy Spirit, who shall so rule your hearts that you find in me true comfort, peace, and joy.
My peace is not given as the world gives peace. The world bases its peace only on transient things, as possessions, power, honor, friendship of men. When these are gone, then peace, confidence, and courage are gone. Though it were in the power of the world to give and preserve all these, yet it has not, nor can it have, true eternal peace, so that a heart enjoys God’s favor and is certain of his grace and of everlasting life. But since this is not the world’s peace, the holy cross is laid upon it; measured by reason and by our feelings, it means no peace, but dissensions, anguish, fear, and trembling. Christ says, “In the world ye shall have tribulation: but be of good cheer; I have overcome the world;” this is to be your peace.
Thus Christ has assured and satisfied his Church with peace that abides in the midst of tribulation and temptation. Therefore, when the heart is oppressed, in anguish and terrified, as if a fugitive before God, this peace must be fixed by faith in the Word of Christ, that it may say: I know that I have God’s pledge and the witness of the Holy Spirit that he wants to be my Father and is not angry with me, but assures me of peace and all good through Christ, his Son.
