Is there a place for Christianity in Todays World

I will be responding not to my opponent's general position - that Christianity has a place in today's world - but rather to his more defined position in his opening. This does not mean I am ignoring his general premise, only that I accepted this debate based on his more refined position in his opening. Unfortunately, I still need clarification on most of his points before I can substantively respond with any depth. I want to avoid falsely presuming I comprehend what he means, even if I feel like I can. -Pro's Positions- "The Christian worldview provides the most fulfilling life here on this planet." After this contention, he does provide some anecdotal support for this position but he does not address what defines a Christian worldview. I would also argue that his position begs the following questions: What constitutes a fulfilling life? And how do we objectively measure the standards by which any given society, as a whole, is leading a fulfilling life? If the answers to these questions are predicated only on Pro's contention that the Christian worldview is the only way of having a fulfilling life, he will need to expand upon that to provide support for what objective standards we use to measure it. Is a fulfilling life one without war? Disease? Depression? Poverty? Happiness? These are important questions to answer in order to evaluate whether a definition of the Christian worldview provides the most fulfillment. "It allows for the forgiveness of sin and provides hope not only now but for eternity." This begs too many questions that that need to be answered because I need proper definitions and qualifications of the meaning: 1) What constitutes sin? 2) Who constitutes as the legislator of what sin is? 3) Why must it be forgiven? 4) Why does the forgiver desire to forgive the forgivee? 5) Does forgiveness of sin improve fulfillment in life? And if so, how? And if how, why? 6) What constitutes hope? 7) What do you mean by eternity (Eternal consciousness? Eternal physical and conscious life?)? 8) Why does being forgiven of sin, and having hope for eternity, equate with a more fulfilling life than other relative worldviews? "If other religions eliminate the self or conclude there is no soul or it is not eternal, what hope does that provide for man's longing as an eternal being?" Again, too many questions for me to posit: 1) What other religions are you speaking of? 2) What do you mean by "eliminate the self"? 3) Have these religions concluded that there is no soul, or it is not eternal? If so, which? 4) How does a conclusion that there is no soul, or it is not eternal, equate with hope, as you define hope? 5) How can one that concludes that the soul is not eternal, long to be an eternal being? [Longing to be an eternal being would require the belief in the possibility of eternity; but that isn't the case if you already don't hold that belief] 6) Why does the lack of belief of a soul, or an eternal soul, equate with a measurable scale of fulfillment? I would provide my own position but I believe that based on Pro's position, I cannot state my position until most of these questions are at least given some attention. I apologize if it sounds like I am deflecting. I just do not want to waste time arguing against the position if I am not clear on what you mean in your own. It would seem fair to both of us to avoid having a disjunctive debate before we get too far into it. Thank you.
