Peter erred in life and in doctrine. Paul might have dismissed Peter's error as a matter of no consequence. But Paul saw that Peter's error would lead to the damage of the whole Church unless it were corrected. Therefore he withstood Peter to his face. The Church, Peter, the apostles, angels from heaven, are not to be heard unless they teach the genuine Word of God.
Martin LutherIf there is anything in us, it is not our own; it is a gift of God. But if it is a gift of God, then it is entirely a debt one owes to love, that is, to the law of Christ. And if it is a debt owed to love, then I must serve others with it, not myself.
Martin LutherThe Holy Spirit is no Skeptic, & the things He has written in our hearts are not doubts or opinions, but assertions - surer & more certain than sense & life itself.
Martin LutherEven if all the world were to combine forces, they could not bring about the conception of a single child in any woman's womb nor cause it to be born; that is wholly the work of God.
Martin LutherFaith is a living, bold trust in God's grace, so certain of God's favour that it would risk death a thousand times trusting in it. Such confidence and knowledge of God's grace makes you happy, joyful and bold in your relationship to God and all creatures. The Holy Spirit makes this happen through faith. Because of it, you freely, willingly and joyfully do good to everyone, serve everyone, suffer all kinds of things, love and praise the God who has shown you such grace.
Martin Luther
