Is there a place for Christianity in Todays World

My opponent brought out some pertinent questions, which I will attempt to tackle at a large scale in order to advance the debate. 1)For a quick definition of Christian worldview, we hold there are 4 basic precepts, 1) a Holy God, the malady of sin, God"s provision of salvation and 4) the works of Christ. (1) 2)For the purpose of our debate let"s suppose a most fulfilling life would be founded not on material gain, and the pursuit of power, position, fame or fortune, but one that is genuinely reward-able to the believer by helping his fellow man, serving the community, caring for one another, because he believes he is an heir in eternal life. He still faces everyday challenges yet considers this belief as an heir, his most cherished gift, thereby he considers himself most fulfilled. 3)As objectively measuring the fulfillment, we can take the believer at his word that he is most fulfilled, it may not be measurable to you or I if it is a belief he holds, (the inheritance). Yet we contend his interaction with society and community advances everyone's well being, including his and still provides him with fulfillment. 4)Yes he is susceptible to war, poverty, disease and still pursuits happiness, yet his lifestyle doesn"t guarantee the elimination of pain, or the assurance in the this life of surplus. Yet he considers himself most blessed of all men. He still hopes for peace and health, and blessings from the providence of God but regardless of those manifestations he claims complete fulfillment. 5)We believe in the inherent depraved nature of man which requires the forgiveness of sin and can only be acquired by faith in the perfect works of a sinless God incarnate, the person and works of Jesus Christ. This is the forgiveness spoken of. God defines sin, God is the legislator. God as the forgiver desires to forgive the forgivee to allow for a relationship once again with his creation, yet un-holiness cannot dwell in His presence, a forgiving process must take place. And yes forgiveness improves fulfillment of life because the person has recognized his eternal inheritance. The person can live out their life without the sting that death brings with it. Personal relationships with family, and loved ones can be permanently maintained even if temporally interrupted. This is one of the greatest fulfillments in this life. 6)We do believe all mankind longs for a relationship with his God and longs for eternal life. This is the hope and longing we speak of. So to several of your concluding questions, such as Do we mean eternal physical and conscious life? (We do, we believe in the resurrection of both the body and soul and continuation of consciousness), and Why does being forgiven of sin, and having hope for eternity, equate with a more fulfilling life than other relative world views? .....we might ask, If you do not believe in the eternal soul, wouldn't the person who is set to gain an eternal life be living a more fulfilled life, knowing he is set to gain that. If life holds anything of intrinsic value and worth, love, happiness, peace, relationships, isn't forever as a quantity of it, better than seventy or eighty years of it? I understand that desire requires believing the possibility first, but what if the understanding came with the worldview? If the promise of this inheritance of eternal life was part of the Christian worldview, that one could accept, once one understood that, wouldn't he then reasonably long for it? In regards to the other religions for the purpose of keeping the debate on track, Buddhism contends, "People cannot satisfy their souls with anything because they do not have souls (i.e. enduring substances) "so the person has no essence; it is only a collection of states called skandas."
