Christianity says that it is possible to know the truth except it's not in the way that many Atheists would like. The Atheist position seems to be " prove this to me and I will have faith in it" whereas Christ says "seek and you will find, knock and the door will be open to you , let me make my home in you and you will know the truth" So what is to stop any Atheist giving it a try? You could think of it like trying a new hobby for a while , or going on a blind date...if it doesn't work out then you can go back to the old ways. Even better you would be able to say "look Christians, I have really really tried it out and it's bunkum" . How many of you have done this? Christianity says the proof is in the pudding , the Atheist dogma seems to be " I'm not gonna try the pudding until you prove it" but what have you got to lose apart from a little pride?
I look forward to lots of 'but I have tried it' responses , this could get interesting
(NB- If any of you are tempted to try this then try and be less rigid with the concept of 'knowing ' the truth. Christianity uses the word know in the sense of the way a man 'knows' his wife (ie intimacy) , not in the sense of knowing that 23x5= 115)
