With God nothing has any standing except grace (#1846). These promises of grace are all based on Christ from the beginning of the world, so that God promises this grace to no one in any other way than in Christ and through Christ (#1845).
No faith is sufficient to save except the Christian faith, which believes in Christ and through Him, and in no other way, receives these two things; satisfaction of divine justice and grace or the bestowal of eternal salvation. Thus says St. Paul (Romans 4:25): "Christ was delivered for our offenses and was raised again for our justification" (#1462). Our faith is an astounding thing - astounding that I should believe Him to be the Son of God who is suspended on the cross, whom I have never seen, with whom I have never become acquainted...But He says in the Gospel: I am a Lord (#1423). There is no other way or means whereby we come to faith than by hearing, learning, and considering the Gospel; (#1417).
The Holy Spirit Himself and God, the Creator of all things, is the Author of this book (#168). I shall and must be convinced by Scripture, not by the unreliable life and teachings of men, no matter how holy they may be (#280). Let the Holy Spirit Himself read this Book to His own if He desires to be understood. For it does not write about men or about making a living as all the other books do, but about the fact the God's Son was obedient to His Father for us and fulfilled His will...the Son of God willingly and obediently became a burnt offering in order to appease God's wrath (#248). It is beyond a doubt that the entire Scripture points to Christ alone (#208).

A Return to Original Foundations
We teach nothing new. We teach what is old and what the apostles and all godly teachers have taught, inculcated, and taught before us. (What Luther Says - para 2689)
Conserving the Good of the Past
The chief reason why we observe...festivals is that the ministry of the Word may be preserved, so that people may come together on certain days and at certain times in order to hear the Word, to learn to know God, to partake of Holy Communion, to pray together for all their needs, and to give thanks to God for all His benefits, both bodily and spiritual. And I believe that for this reason, above all, the fathers' instituted the observance of the Lord's Day, Easter, Pentecost, etc. (What Luther Says - para 2691)
FAITHLESS FRIENDS WORSE THAN FURIOUS FOES
Our church will not be endangered as greatly by the oppressive measures of tyrants as by the indifference of our own people. (What Luther Says - para 2714)
"If the article of justification is lost, all Christian doctrine is lost at the same time...for there is no middle ground between these two righteousnesses; the active one of the Law and the passive one which comes from Christ. Therefore the man who strays from Christian righteousness must relapse into the active one, that is, since he has lost Christ, he must put his confidence in his own works.
(What Luther Says, p. 702, para 2194).
To pray aright is a very difficult task and the art supreme. It is not so because of the words of the mouth. But for the heart to be able by itself to conclude with certainty and assurance that it may step before God with complete confidence and say; "Our Father" - that is a task.
(What Luther says - para 3477 - pp. 1088)
When you call upon Jesus Christ and say: O my dear Lord God, my Creator and Father, Jesus Christ, Thou one eternal God, you need not worry that the Father and the Holy Spirit will be angry on this account. They know that no matter which Person you call upon, you call upon all three Persons and upon the One God at the same time. For you cannot call upon one Person without calling upon the others, because the one, undivided divine Essence exists in all and in each Person. Conversely, you cannot deny any Person in particular without denying all three and the One God in His entirety, as I John 2:23 says: "Whosoever denieth the Son, the same hath not the Father."
(What Luther Says - para 3454, pp. 1082)
