i am not sure if i can answer that question since i am not a convert. but what i have learnt from my discussions about islam with my non-muslim friends is that faith is not a matter of logic. its about pure inner conviction. i may be able to win the argument and prove that islam is the right religion but that would not be good enough for someone to convert to islam. however, if you have the conviction that this is it, there won't be any disappointments.
