基督徒是如何成全律法的？
相信基督之愛和恩寵之時，聖靈就感動我們的心靈去愛上帝，並會喜樂地作它應做的工。
看啦！這就是福音教義的能力和我們賴以得救的寶藏。它帶領我們到達可以開始成全律法的地步了。因為在哪裡傳揚這偉大的、不可戰勝的基督之愛和恩寵，當它被相信時，那裡就湧流出對上帝和鄰舍的愛。藉著這知識的安慰，聖靈就感動我們的心靈去愛上帝，並會喜樂地作它應做的工，就是：讚美和感謝主；抵擋罪和不順服；樂意將自己獻上；服事和幫助所有人；與肉體和撒旦作戰；在它軟弱之處呼求上帝；等等。當心靈在信心裏甦醒，抓住基督時，當它沒有完全遵循律法時，它的安慰就是：基督成全了律法，他又賜下他的完全，他的能力也參與作工，因此主總是我們的義、拯救、成聖，等等。——馬丁路德
（《講道集》第五卷，John Lenker編輯，p. 40，五旬節第十三主日講道，路加福音10:23-37）
Behold, this is the doctrine and the power of the Gospel and the treasure by which we are saved; which brings us to the point that we also begin to fulfill the law. For where the great unfathomable love and favor of Christ are known and believed, thence flows forth also love both to God and to our neighbor. For by means of such knowledge and consolation the Holy Spirit moves the heart to love God, and gladly does what it should to his praise and thanks, guards against sin and disobedience and willingly offers itself to serve and help everybody, and where it still feels its weakness it battles against the flesh and satan by calling upon God, etc. And thus while ever rising in faith it holds to Christ, where it does not do enough in keeping the law, its comfort is that Christ fulfills the law and bestows and imparts his fullness and strength, and thus he remains always our righteousness, salvation, sanctification, etc.
(Sermons by Martin Luther, Vol. 5, by John Lenker, p.40, sermon for Trinity 13 on Luke 10:23-37)
