So present your best reasons for your belief, so I may evaluate them....
Sorry for the brevity of personal response here, in this case, it might be for the best to save on time and space (considering it's going off topic, but because you asked...). Before I post the relevant links though, here is a short little story about a period of time in my life. Between 2001-2003 I spent a great deal of time debating atheists/agnostic and just about anyone I found disagreement with. I learned a great deal of things in the process, I learned from them and from outside study and research. At the time I was a Weslyian/Pentecostcal type, and in defending the faith, I leaned heavily on a Classical/Rational approach while paying attention to evidential/historical approaches, and honestly had mostly disdain for the fideist approach. So anyway, after a couple of years of this, and mostly privately conceding many things, I came to realize the weakness of the approach I used, weakness may be putting it nicely. For example, the realization set in on just how little each of the arguments taken as single arguments substantiate, and here I was a Christian with a very nuanced and specific God with so many doctrines and other specifics to a Christian worldview, and how woefully short these arguments fell from proving that the God that exists is the God of Christianity. My whole thinking crumbled apart, I realized the probabilities involved in the arguments and how these arguments always leave a backdoor open, always. Even one of my favorite arguments, the moral argument for the existence of God, the main thrust of your thread here, I came to realize the difficulty in proving moral absolutes (though I do have a couple of gross examples, rather not go there). I actually came to a point where everything just shattered into a million pieces. To say I was experiencing doubts is an understatement, I began questioning everything I held dear, including my faith. Could I know anything with certainty? Does it all boil down to faith and probabilities? Agnosticism was setting in, and there was little I could do to prevent it. Feeling hopeless and discouraged, I decided to looking into other approaches outside of my Wesleyan box. I loaded a software disc in my PC that has an entire collection of lectures by a man by the name of Cornelius Van Til and although the quality was terrible, I suffered through and started listening and listening, and lights were clicking on even though I could hardly understand every little detail, nonetheless changes were taking place, tears were in my eyes, and I began to realize, "this man is speaking the truth, he knows what he is talking about, he is being faithful to Scripture in the whole process". Through and because of this crisis of faith, I became a convinced Calvinist, and a convinced presuppositionalist. Now many years later while I am a presuppositionalist, it's inspired me to take a more integrated approach, with an appreciation for the arguments from each of the approaches, while a Christian presuppositionalism is the methodology underneath or behind the various arguments. In other words, the traditional arguments are supportive and perfectly valid within a Christian worldview, even encouraging and uplifting, however when used as single arguments in order to prove the God of Christianity, their individual weakness is exposed. Chained together they make a much stronger case, but still will not convince the already convinced non-believer. The primary need for man is regeneration or "the new birth" or the "born again" experience. Without the ears to hear, without a softened heart, without the light of Christ, we remain in darkness and love the darkness and remain in enmity with God in the carnality of our minds. I could go on, but I will leave it at that and provide a few links to resources going into some detail concerning my faith and reasons with more depth than I am able to go into and saving on time and space.
