Only hearing brings joy.
This is the only way for the heart to find peace before God. Everything else that it can undertake leaves doubt in the mind… the forgiveness of sins becomes actual not through works but through hearing…
On this do I build, that God says to me through the brother: ‘I absolve you in the name and merit of Christ.’ I believe this word is true, nor will my faith fail me.
It is ‘built on the rock of the words of the Son of God,’ who cannot lie because He is the Truth. In this way your minds are filled with joy and the true gladness of the Holy Spirit, which consits wholly in the certainty of the Word in hearing.”
