Martin Luther, one of history’s great men of faith in Christ, took a wrong turn. The results in human history have been devastating. His achievements are many, and they have endured across time. Sadly, so have his flaws. Martin Luther let an age-old evil rise up within him, and it wound up ruling a significant part of his life and legacy. At one point, it practically destroyed his German homeland. The old evil was an unreasoning hatred for Jews.
