" But what, then, is original sin? According to the Apostle it is not only the lack of a good quality in the will, nor merely the loss of man’s righteousness and ability. It is rather the loss of all his powers of body and soul, of his whole outward and inward perfections. In addition to this, it is his inclination to all that is evil, his aversion against that which is good, his antipathy against light and wisdom, his love for error and darkness, his flight from and his loathing of good works, and his seeking after that which is sinful. Thus we read in Psalm 14:3: “They are all gone aside, they are all together become filthy; there is none that doeth good, no, not one”; and in Genesis 8:21: “The imagination of man’s heart is evil from his youth.” Actual sins essentially consist in this that they come from out of us, as the Lord says in Matthew 15:19: “Out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies.” But original enters into us; we do not commit it, but we suffer it. We are sinners because we are the sons of a sinner. A sinner can beget only a sinner, who is like him. "

" With reference to the elect we might distinguish between three classes. First, there are those who are satisfied with God’s will, as it is, and do not murmur against God, but rather believe that they are elected. They do not want to be damned. Secondly, there are those who submit to God’s will and are satisfied with it in their hearts. At least they desire to be satisfied, if God does not wish to save, but reject them. Thirdly, there are those who really are ready to be condemned if God should will this. These are cleansed most of all of their own will and carnal wisdom. And these experience the truth of Canticles 8:6: “Set me as a seal upon thine heart, as a seal upon thine arm: for love is strong as death.” Such love is always joined with cross and tribulation, for without it the soul becomes lax, and does not seek after God, nor thirst after God, who is the Fountain of Life. "

" In these words the Apostle sets forth a most apt antithesis: first, he who is justified by faith has peace with God, but tribulation with the world, because his life is spiritual. Secondly, the unrighteous have peace with the world, but anguish and tribulation with God, because their life is carnal. Thirdly, as God the Holy Spirit is eternal, so also the peace of the righteous and the tribulation of the unrighteous will be everlasting. Lastly, as the flesh is temporal, so also the tribulation of the righteous and the peace of the unrighteous will be temporary. "
