The upright, in whom the law has exercised its work, when they feel their sickness and weakness, say: God will help me; I trust in him; I build upon him; he is my rock and hope.
The kingdom of Christ is realized where nothing but comfort and the forgiveness of sins reign not only in words to proclaim it, which is also necessary; but also in deed.
You say: Since forgiveness depends on faith alone, why must one nonetheless do good works? Answer: If faith is of the true sort, it cannot be without good works, just as no good work can be where unbelief dwells.
