Luther never taught “easy believism”.
Luther taught a life under the cross, which is a life of discipleship of following after Christ. Our crosses though, do not save. They serve the neighbor. We are called to be neighbor to those around us. Luther says,
“We receive Christ not only as a gift by faith, but also as an example of love toward our neighbor, whom we are to serve as Christ serves us. Faith brings and gives Christ to you with all his possessions. Love gives you to your neighbor with all your possessions. These two things constitute a true and complete Christian life; then follow suffering and persecution for such faith and love, and out of these grows hope and patience.”
Martin sure Lived his word:
I had made up my mind to write no more either about the Jews or against them. But since I learned that these miserable and accursed people do not cease to lure to themselves even us, that is, the Christians, I have published this little book, so that I might be found among those who opposed such poisonous activities of the Jews who warned the Christians to be on their guard against them. I would not have believed that a Christian could be duped by the Jews into taking their exile and wretchedness upon himself. However, the devil is the god of the world, and wherever God’s word is absent he has an easy task, not only with the weak but also with the strong. May God help us. Amen.
He did not call them Abraham’s children, but a “brood of vipers” [Matt. 3:7]. Oh, that was too insulting for the noble blood and race of Israel, and they declared, "He has a demon’ [Matt 11:18]. Our Lord also calls them a “brood of vipers”; furthermore in John 8 :39,44] he states: "If you were Abraham’s children ye would do what Abraham did… You are of your father the devil. It was intolerable to them to hear that they were not Abraham’s but the devil’s children, nor can they bear to hear this today.
Therefore the blind Jews are truly stupid fools…
Now just behold these miserable, blind, and senseless people.
…their blindness and arrogance are as solid as an iron mountain.
Learn from this, dear Christian, what you are doing if you permit the blind Jews to mislead you. Then the saying will truly apply, “When a blind man leads a blind man, both will fall into the pit” [cf. Luke 6:39]. You cannot learn anything from them except how to misunderstand the divine commandments…
Therefore be on your guard against the Jews, knowing that wherever they have their synagogues, nothing is found but a den of devils in which sheer self*glory, conceit, lies, blasphemy, and defaming of God and men are practiced most maliciously and veheming his eyes on them.
Moreover, they are nothing but thieves and robbers who daily eat no morsel and wear no thread of clothing which they have not stolen and pilfered from us by means of their accursed usury. Thus they live from day to day, together with wife and child, by theft and robbery, as arch*thieves and robbers, in the most impenitent security.
However, they have not acquired a perfect mastery of the art of lying; they lie so clumsily and ineptly that anyone who is just a little observant can easily detect it. But for us Christians they stand as a terrifying example of God’s wrath.
If I had to refute all the other articles of the Jewish faith, I should be obliged to write against them as much and for as long a time as they have used for inventing their lies** that is, longer than two thousand years.
…Christ and his word can hardly be recognized because of the great vermin of human ordinances. However, let this suffice for the time being on their lies against doctrine or faith.
Did I not tell you earlier that a Jew is such a noble, precious jewel that God and all the angels dance when he farts?
Alas, it cannot be anything but the terrible wrath of God which permits anyone to sink into such abysmal, devilish, hellish, insane baseness, envy, and arrogance. If I were to avenge myself on the devil himself I should be unable to wish him such evil and misfortune as God’s wrath inflicts on the Jews, compelling them to lie and to blaspheme so monstrously, in violation of their own conscience. Anyway, they have their reward for constantly giving God the lie.
No, one should toss out these lazy rogues by the seat of their pants.
…but then eject them forever from this country. For, as we have heard, God’s anger with them is so intense that gentle mercy will only tend to make them worse and worse, while sharp mercy will reform them but little. Therefore, in any case, away with them!
