If God is to create or to preserve a creature, God must be present and must make and preserve God's creation both in its innermost and outermost aspects.
Martin LutherThere is on earth among all dangers, no more dangerous thing than a richly endowed and adroid reason, especially if she enters into spiritual matters which concern the soul and God. For it is more possible to teach an ass to read than to blind such a reason and lead it right; for reason must be deluded, blinded, and destroyed.
Martin LutherThe Deceiver can magnify a little sin for the purpose of causing one to worry, torture, and kill oneself with it. This is why a Christian should learn not to let anyone easily create an evil conscience in him. Rather let him say, "This error and this failing pass away with my other imperfections and sins, which I must include in the article of faith: I believe in the forgiveness of sins.
Martin LutherWhen we hear that Christ was made a curse for us, let us believe it with joy and assurance. By faith Christ changes places with us. He gets our sins, we get His holiness.
Martin LutherI am much afraid that the schools will prove the very gates of hell, unless they diligently labour in explaining the Holy Scriptures, and engraving them in the hearts of youth. I advise no one to place his child where the scriptures do not reign paramount. Every institution in which means are not unceasingly occupied with the Word of God must be corrupt.
