Errrr...so you've decided there are parts of the Bible you don't believe any more? Or you've decided you believe them but it's bad PR to talk about them?
Let's see now. You are an atheist, but you can quote the Bible. OK, let's go. Of course, this may take a while, what with me going to church 'n all. But, it will give you more time to prepare.
First, let me try to explain MY God and my Bible. At first there was the Old Testament, given to help people survive. It spoke of turmoil and what was necessary to overcome and prosper. Take a look at Jeremiah, Chapter 50 and remember that, what once was Babylon, is now Iraq.
It also spoke of the future, and what was necessary to be a part of that future. It prophesied the coming of our Saviour.
The New Testament tells the story of Jesus, the Lamb of God. Do you understand what that means? Jesus was our sacrifice. Jesus died so that anyone, ANYONE, that accepted him into their heart, was saved. Start with Acts, Chapter 9.
But, my favorite verse is John 3:16. It slapped me across the face a few years ago, and I'll carry it with me always. Got to go now. See you later.
