Whilst a man is persuaded that he has it in his power to contribute anything, be it ever so little, to his salvation, he remains in carnal self-confidence; he is not a self-despairer, and therefore is not duly humbled before God, he believes he may lend a helping hand in his salvation, but on the contrary, whoever is truly convinced that the whole work depends singly on the will of God, such a person renounces his own will and strength; he waits and prays for the operation of God, nor waits and prays in vain
Martin LutherIn ourselves, we are sinners, and yet through faith we are righteous by the imputation of God. For we trust him who promises to deliver us, and in the meantime struggle so that sin may not overwhelm us, but that we may stand up to it until he finally take it away from us.
Martin LutherMen are not made religious by performing certain actions which are externally good, but they must first have righteous principles, and then they will not fail to perform virtuous actions.
Martin Luther
