God does not love sinners because they are attractive; sinners are attractive to God because he loves them.
Martin LutherWhen God's righteousness is mentioned in the gospel, it is God's action of declaring righteous the unrighteous sinner who has faith in Jesus Christ. The righteousness by which a person is justified (declared righteous) is not his own but that of another, Christ.
Martin LutherAlthough the Christian is thus free from all works, he ought in this liberty to empty himself, take upon himself the form of a servant, be made in the likeness of men, be found in human form, and to serve, help and in every way deal with his neighbor as he sees that God through Christ has dealt and still deals with him.
Martin LutherI was born to fight devils and factions. It is my business to remove obstacles, to cut down thorns, to fill up quagmires and to open and make straight paths. If I must have some failing let me rather speak the truth with too great sincerity than once to act the hypocrite and conceal the truth.
Martin Luther
