The fact that you are even having these questions may be an indication in itself.
If those questions were really, really important - say a matter of eternal life and death - shouldn't the answers have been made abundantly clear to everyone millennia ago?
Would any loving God leave people in doubt about if the answers made the difference between 'salvation' and 'destruction'?
Do the many people in countries with a non-Christian culture (like China, India, etc.etc.) have any chance a finding these questions, let alone the answers? They may never even meet a Christian or see a Bible in their lifetime...
Or...what if it's the Christians who are mistaken, asking the wrong questions - about Jesus - therefore never finding the true way to salvation?
So many questions, and the lack of answers from above is both overwhelming and convincing...(at least to me)
