Hereby we may understand that God, of His special grace, maketh the teachers of the gospel subject to the Cross, and to all kinds of afflicitons, for the salvation of themselves and of the people; for otherwise they could by no means beat down this beast which is called vain-glory.
Martin LutherGod wants our conscience to be certain and sure that it is pleasing to Him. This cannot be done if the conscience is led by its own feelings, but only if it relies on the Word of God.
Martin LutherIf the devil were wise enough and would stand by in silence and let the gospel be preached, he would suffer less harm. For when there is no battle for the gospel it rusts and it finds no cause and no occasion to show its vigor and power. Therefore, nothing better can befall the gospel than that the world should fight it with force and cunning.
Martin Luther
