You know the real basis and foundation of your salvation, on which you must rest your confidence in this and all troubles, namely Jesus Christ, the cornerstone.
He will not waver or fail us, nor allow us to sink and perish, for He is the Saviour and is called the Saviour of all poor sinners, of all who face tribulation and death, of all who rely on Him and call on His name.
He says, “Be of good cheer; I have overcome the world.” (John 16:33)
If He has overcome the world, surely He has overcome the prince of this world with all His power. And what is His power but death, with which He has made us subject to Him, captives on account of our sin?
But now that death and sin are overcome, we may joyfully and cheerfully listen to the sweet words, “Be of good cheer; I have overcome the world.”
And we must not doubt that they are certainly true. More than that, we are commanded to accept their comfort with joy and thanksgiving.
Whoever is unwilling to be comforted by these words does the greatest injustice and dishonor to the Comforter— as if it were not true that He bids us to be of good cheer, or as if it were not true that He has overcome the world.
If we act thus, we only restore within ourselves the tyranny of the vanquished devil, sin, and death, and we oppose the dear Saviour. From this may God preserve us!
Therefore, let us rejoice with all assurance and gladness. Should any thought of sin or death frighten us, let us lift up our hearts and say:
“Behold, dear soul, what are you doing? Dear death, dear sin, how is it that you are alive and terrify me? Do you not know that you have been overcome?
Do you, death, not know that you are quite dead? Do you not know the One who has said of you, I have overcome the world?
It does not behoove me to listen to or heed your terrifying suggestions. I shall pay attention only to the cheering words of my Saviour, ‘Be of good cheer, be of good cheer; I have overcome the world.’
He is the Conqueror, the true Hero, who in these words, ‘Be of good cheer,’ gives me the benefit of his victory. I shall cling to Him.
To His words and comfort I shall hold fast. Whether I remain here or go yonder, He will not forsake me.
You would like to deceive me with your false terrors, and with your lying thoughts you would like to tear me away from such a Conqueror and Saviour.
But they are lies, as surely as it is true that He has overcome you and commanded us to be comforted.”
This is also the boast of Saint Paul and his defiance of the terrors of death:
‘Death is swallowed up in victory. O death, where is thy sting? O grave, where is thy victory?’ (1 Cor. 15:55)
Like a wooden image of death, you can terrify and frighten, but you have no power to destroy. For your victory, sting, and power have been swallowed up in Christ’s victory.
You can show your teeth, but you cannot bite. For God has given us the victory over you through Christ Jesus our Lord, to whom be praise and thanks. Amen.’
With such words and thoughts, and with none other, you may set your heart at rest, dear mother.
Be thankful that God has brought you to such knowledge and not allowed you to remain in papal error, by which we were taught to rely on our own works and the holiness of the monks and to consider this only comfort of ours, our Saviour, not as a comforter but as a severe judge and tyrant, so that we could only flee from Him to Mary and the saints and not expect of Him any grace or comfort.
But now we know differently about the unfathomable goodness and mercy of our Heavenly Father.
We now know that Jesus Christ is our mediator, our throne of grace, and our bishop before God in heaven, who daily intercedes for us and reconciles all who call upon and believe in Him.
We now know that He is not a grim judge, except to those who do not believe in Him and who reject His comfort and grace.
We now know that He is not the Man who accuses and threatens us, but rather that He intercedes for and reconciles us by His own death, having shed His blood for us in order that we might not fear Him but approach Him with all assurance and call Him our dear Saviour, our sweet Comforter, the true Bishop of our souls.”
