Martin Luther, On Christian Liberty Quotes
A Christian is a perfectly free lord of all, subject to none. A Christian is a perfectly dutiful servant of all, subject of all, subject to all.
The soul can do without everything except the word of God, without which none at all of its wants are provided for.
To preach Christ is to feed the soul, to justify it, to set it free, and to save it, if it believes the preaching.
