These words by Martin Luther should stand as reminder to us all that end times forecasting is worthless - unless you are viewing the "End Times" as the whole period after His Resurrection. First published in 1522, the excerpts are the 6th and 7th paragraphs of his sermon titled: Christ's Second Coming: or the Signs of the Day of Judgment; and the Comforts Christians Have From Them:
I do not wish to force any one to believe as I do; neither will I permit anyone to deny me the right to believe that the last day is near at hand. These words and signs of Christ compel me to believe that such is the case. For the history of the centuries that have passed since the birth of Christ nowhere reveals conditions like those of the present. There has never been such building and planting in the world. There has never been such gluttonous and varied eating and drinking as now. Wearing apparel has reached its limit in costliness. Who has ever heard of such commerce as now encircles the earth? There have arisen all kinds of art and sculpture, embroidery and engraving, the like of which has not been seen during the whole Christian era.
In addition men are so delving into the mysteries of things that today a boy of twenty knows more than twenty doctors formerly knew. There is such a knowledge of languages and all manner of wisdom that it must be confessed, the world has reached such great heights in the things that pertain to the body, or as Christ calls them, "cares of life", eating, drinking, building, planting, buying, selling, marrying and giving in marriage, that every one must see and say either ruin or a change must come. It is hard to see how a change can come. Day after day dawns and the same conditions remain. There was never such keenness, understanding and judgment among Christians in bodily and temporal things as now - I forbear to speak of the new inventions, printing, fire-arms, and other implements of war...This compels me to believe that Christ will soon come to judgment...it must soon break in upon them.
