The Holy Spirit is no skeptic. He has written neither doubt nor mere opinion into our hearts, but rather solid assurances, which are more sure and solid than all experience and even life itself.
Martin LutherDearest Jesus, holy child, make thee a bed, soft, undefiled, within my heart, that it may be a quiet chamber kept for thee.
Martin LutherFather and Mother are apostles, bishops and priests to their children, for it is they who make them acquainted with the gospel.
Martin LutherAlso when it is a case of only upholding some spiritual tenet, such as infant baptism, original sin, and unnecessary separation, then . . . we conclude that . . . the stubborn sectaries must be put to death.
Martin LutherThe devil is not only a liar, but also a murderer, he constantly seeks our life, and wreaks his anger whenever he can afflict our bodies with misfortune and harm. Hence it comes that he often breaks men's necks or drives them to insanity, drowns some, and incites many to commit suicide, and to many other terrible calamities. Therefore there is nothing for us to do upon earth but to pray against this arch enemy without ceasing. For unless God preserved us, we would not be safe from him even for an hour.
Martin Luther
