Then they began to say: 'Yes, but how can we know what is God's Word, and what is right or wrong? We must learn this from the Pope and the councils.' Very well then, let them conclude and say what they please, yet I will reply, you cannot put your confidence in that nor thus satisfy your conscience, for you must determine this matter yourself, for your very life depends upon it. Therefore God must speak to your heart: This is God's Word; otherwise you are undecided.
Martin LutherThe will of man without grace is not free, but is enslaved, and that too with its own consent.
