Creepily enough, one of the most horrible people who ever lived spoke loftily about God as a way to disguise his true nature. The 700 Club has put together a powerful resource on this at:
Here are a few excerpts:
Was Adolf Hitler a Christian?
Throughout history, politicians have used religious language to win elections. One world leader was particularly good at it:
“In this hour I would ask of the Lord God only this: that He would give His blessing to our work, and that He may ever give us the courage to do the right. I am convinced that men who are created by God should live in accordance with the will of the Almighty. No man can fashion world history unless upon his purpose and his powers there rests the blessings of this Providence.”
That may sound like an ideal leader, but that speech was given in 1937 by the Chancellor of Germany, Adolf Hitler. In his speeches, he challenged people to love their neighbors, to care for the poor and sick, and to take a stand against violence.
We need to be careful of people claiming to be God-fearing Christians while doing evil things. When Christianity is attacked because of the bad actions of such ravening wolves, you can say,
“Wait, is what you’re attacking really Christianity? Is that person doing the will of God? Or are they just claiming they’re faithful to God in order to promote their evil deeds? You can tell by looking at the FRUIT.”
Jesus taught us a clear way to discern the truth of whether or not a particular person, ministry, or doctrine is legitimately following the will of God: A good tree will bear good fruit, and a bad tree will bear bad fruit. It’s that simple.
When in doubt over someone’s religious claims, look closely at the fruit those claims are producing in that person’s life, ministry, and professional, political, and personal outcomes. By this measure, a lot of people who claim to be Christians, such as Hitler, are, on closer inspection, nothing but bad trees fruit trees producing toxic fruit. (Apple with a bite out of it, anyone?)
Jesus said someday he will tell all those people who have used his name to produce bad fruit to depart, since he never knew them.
A Tree and its Fruit Matthew 7:15-23
15Beware of false prophets, which come to you in sheep’s clothing, but inwardly they are ravening wolves. 16Ye shall know them by their fruits. Do men gather grapes of thorns, or figs of thistles? 17Even so every good tree bringeth forth good fruit; but a corrupt tree bringeth forth evil fruit. 18A good tree cannot bring forth evil fruit, neither can a corrupt tree bring forth good fruit. 19Every tree that bringeth not forth good fruit is hewn down, and cast into the fire. 20Wherefore by their fruits ye shall know them.
21Not every one that saith unto me, Lord, Lord, shall enter into the kingdom of heaven; but he that doeth the will of my Father which is in heaven. 22Many will say to me in that day, Lord, Lord, have we not prophesied in thy name? and in thy name have cast out devils? and in thy name done many wonderful works? 23And then will I profess unto them, I never knew you: depart from me, ye that work iniquity.
