Before I respond to this I would like to say that all human beings are worthy of repectful treatment. Personally I have never had an issue responding to any questions like that. There are of course folks out there that will make you think and explore the depths of your faith but that is a good thing. Luk 12:11 And when they bring you unto the synagogues, and unto magistrates, and powers, take ye no thought how or what thing ye shall answer, or what ye shall say: Luk 12:12 For the Holy Ghost shall teach you in the same hour what ye ought to say. If one spends enough time in the presence of his Father then the Holy Spirit will help that one speak the words of life that will reach even the hardest of hearts.
