I'm sure that millions of them believed in God as strongly as you claim to.
This country was formed by Christians(only one in history that used Biblical Principles) with GOD’S Help’
There is only one GOD, THE GOD OF THE BIBLE.
It was not Christians who killed all those people.
WE have more Bibles in the USA then in all the World.
You may not believe that GOD is involved in our daily lives but a lot of freepers would tell you different.
Among the butchers you name, some were likely believers in God and yet still denied him.
The more I debate atheists, the more I come to realize most of them fall into this category, not the category of nonbelief.
From Hebrews 11:
32 And what more shall I say? I do not have time to tell about Gideon, Barak, Samson and Jephthah, about David and Samuel and the prophets, 33 who through faith conquered kingdoms, administered justice, and gained what was promised; who shut the mouths of lions, 34 quenched the fury of the flames, and escaped the edge of the sword; whose weakness was turned to strength; and who became powerful in battle and routed foreign armies. 35 Women received back their dead, raised to life again. There were others who were tortured, refusing to be released so that they might gain an even better resurrection. 36 Some faced jeers and flogging, and even chains and imprisonment. 37 They were put to death by stoning;[e] they were sawed in two; they were killed by the sword. They went about in sheepskins and goatskins, destitute, persecuted and mistreated 38 the world was not worthy of them. They wandered in deserts and mountains, living in caves and in holes in the ground.
39 These were all commended for their faith, yet none of them received what had been promised, 40 since God had planned something better for us so that only together with us would they be made perfect.
Not to mention "Eloi, Eloi, lama sabachthani?"
Cheers!
