salam alaikum,
I don't think Deedat is saying that. I think his main point is there was no witness there to see him on the cross and there is no proof he died on the cross or was even there in the first place. all the accounts of the crucifixion differ and contradict each other in some ways, which should, to a logical person, cast doubts on how reliable the story is.
I come from a Christian background, and for me what convinced me the Bible wasn't the truth wasn't someone sitting down and disproving verses, but rather looking at the history of the Bible and early Christianity and how it came to be in its current form. I don't know how someone could know how the Bible was compiled and still believe that it's all true and reliable. Once I learned that it became impossible for me to take anything from the Bible seriously. Especially the crucifixion. Maybe you could go that route if all else fails?
Thank you kayleigh for your attention to my cause.
It seems like my wife relies on King James version of the bible. She said Peter was with him the whole time.
"And Peter followed him afar off, even into the palace of the high priest: and he sat with the servants" Mark 14:54
I hope you guys will not get frustrated with me. It's my wife that I'm having to battle on this with.
Dear Brother i can feel your desperation in which situation you are in.Well i will sugest you that when ever you you want or start talking with you wife regarding Islam first make wudu and make dua to Allah SWT if you can.Because with HIS SWT help no body in this world can change his or her mind.I have read things you have written regarding you less knowledge on Islam, thats really not a problem.What ever knowledge you have share with it with good manner,Inshallah she can understand, but do make salah in front of her and read Quran with meaning so that word could hit her ears.Because many people espaicially christian they are taught or made them understand how to contradic with Islam. But dont worry about this as truth is always a noor.And one more thing be confident on what ever part of hadith Quran you say atleast you should have best knowledge of what knowledge you have. And one more thing i want to say before ending that when ever you face a problem on a topic which you dont know, just simply escuse your self dont ever try to proof iit and your way or any other mean, as just wouldnt be aware of what problem you would face next.
I pray and ask Allah to guide her heart and to make my task easy on me and help me with it.

. So, you should better focus yourself on providing your wife proofs of Qur'an authenticity, and there are plenty of them. Because, even if you proof to her that Bible isn't from Allah, then you still don't have the proof for Islam, and that won't make her any more near to Islam. Also, if you have some questions, try contacting this brother:
