This should make us very easy to convert with the following three-step process:
- Produce the evidence that you found convincing.
- Explain why it is evidence only for your god and not any other. Since people have believed in over 3000 different gods in recorded human history, obviously you will need to show why your evidence couldn't be evidence for any of those.
- Explain how a god is the only possible explanation for your evidence and why it can't possibly be explained as the result of a natural process.
Now, since, presumably, you were convinced of your god's existence by just such evidence and just such a process, it shouldn't be too difficult to tell us Atheists where it's to be found and how it meets the above criteria.
In your own time....
(p.s. Opinion isn't evidence and nor is a quote from a book unless the quote refers to authenticated, observable evidence meeting the above criteria).
If you can't find any such evidence or provide any of this explanation, maybe you should be asking yourself why you believe in your god, because one thing is certain: your belief isn't based on evidence or rational analysis... so what is it based on exactly?
[Later note] It seems many Creationists are unsure of what constitutes 'evidence' and imagine it includes ignorance and even the opinions of others. The following blogs may help them gain the necessary understanding to be able to use the above method:
