The Bible is the proper book for men. There the truth is distinguished from error far more clearly than anywhere else, and one finds something new in it every day. For twenty-eight years, since I became a doctor, I have now constantly read and preached the Bible; and yet I have not exhausted it but find something new in it every day.
Martin LutherSo tenaciously should we cling to the world revealed by the Gospel, that were I to see all the Angels of Heaven coming down to me to tell me something different, not only would I not be tempted to doubt a single syllable, but I would shut my eyes and stop my ears, for they would not deserve to be either seen or heard.
Martin LutherIf I had to refute all the other articles of the Jewish faith, I should be obliged to write against them as much and for as long a time as they have used for inventing their lies - that is, longer than two thousand years.
Martin LutherIn Romans 7, St. Paul says, "The law is spiritual." What does that mean? If the law were physical, then it could be satisfied by works, but since it is spiritual, no one can satisfy it unless everything he does springs from the depths of the heart. But no one can give such a heart except the Spirit of God, who makes the person be like the law, so that he actually conceives a heartfelt longing for the law and henceforward does everything, not through fear or coercion, but from a free heart.
Martin LutherThere are some of us who think to ourselves, 'If I had only been there! How quick I would have been to help the Baby. I would have washed His linen. How happy I would have been to go with the shepherds to see the Lord lying in the manger!' Why don't we do it now? We have Christ in our neighbor.
