Luther's comfort when hated by the world

Therefore it should not affect us if the world, whose works we declare to be evil, judges that we are the most dangerous heretics and insurrectionists, overthrowers of religion and of the public peace, and possessed by the devil, who speaks through us and governs all our actions. In opposition to this perverse judgment of the world let us be satisfied with the testimony of our conscience, by which we know as a certainty that it is a divine gift when we not only believe in Jesus Christ but proclaim and confess him openly in the presence of the world. As we believe in our hearts, so we speak with our lips, according to the statement of the psalm (116:10): “I believed, and so I spoke; but I am greatly afflicted.”

– Martin Luther, 1535 Lectures on Galatians, AE 26:375
