Context: If you are a preacher of mercy, do not preach an imaginary but the true mercy. If the mercy is true, you must therefore bear the true, not an imaginary sin. God does not save those who are only imaginary sinners. Be a sinner, and let your sins be strong (sin boldly), but let your trust in Christ be stronger, and rejoice in Christ who is the victor over sin, death, and the world. We will commit sins while we are here, for this life is not a place where justice resides. We, however, says Peter (2. Peter 3:13) are looking forward to a new heaven and a new earth where justice will reign.
Martin Luther: Sin
Martin Luther was seminal figure in Protestant Reformation. Explore interesting quotes on sin.
Widely attributed to Luther, but actually is an example given in 1658 book Ἑρμηνεια logica https://books.google.com/books?id=2MxlAAAAcAAJ&pg=PA228| of faulty logic. In Latin:
Si vero termini in sorite sunt causae subordinatae per accidens, sorites non valet; ut ia hoc, Qui bene bibit, bene dormit; qui bene dormit, non peccat; qui non peccat, est beatus; ergo: qui bene bibit est beatus. Vitium est, quod bene bibere sit causa per accidens somni.
Translated via Fauxtations https://fauxtations.wordpress.com/2016/08/21/drinking-and-not-sinning/:
If, however, the conclusions in the sorite are subordinate by accident, the sorites is not valid; as in this one, He who sleeps well, drinks well; he who sleeps well, does not sin; he who does not sin, is blessed; therefore, he who drinks well is blessed. The problem is that to drink well is a cause of sleep only by accident.

Context: As David said, “Against thee, thee only, have I sinned, so that thou art justified in thy sentence” [Ps. 51:4]. As a matter of fact, true Christians willingly accept the rebuke and judgment that is in the preaching of God’s word. But those who won’t receive this judgment show plainly that they are really damnable knaves. They are sinning against the Holy Spirit when they refuse to accept the rebuke of the preachers through whom he speaks. Or they are so far gone that they regard our preaching as nothing more than man’s word and so won’t tolerate it.
