Let all the 'free-will' in the world do all it can with all its strength; it will never give rise to a single instance of ability to avoid being hardened if God does not give the Spirit, or of meriting mercy if it is left to its own strength.
Martin LutherThe sin underneath all our sins is to trust the lie of the serpent that we cannot trust the love and grace of Christ and must take matters into our own hands
Martin LutherThe article of justification is fragile. Not in itself, of course, but in us. I know how quickly a person can forfeit the joy of the Gospel.
