Of Religion and Spirituallity

Since I started going to college last year I have had my eyes opened to a lot of things, one in particular is the way most people view Christianity, or religion in general.

Yesterday was one of those days, I was sitting around with some friends, most of whom are in my world religions class and one who is a Religious Studies major at MSU, and the topic turned to the personal religious beliefs of those present, most of what I heard was not surprising, but there was one thing that stuck out to me and that was that these women were all tired of organized religion and were searching for something deeper more personal. I was at a loss for what to say, on so many levels I agreed with them, our churches have lost sight of what it means to have a personal relationship with Christ and have focused so heavily on rituals/tradition and appearance that these women equated church and the Bible with a bunch of rules that you have to follow. They didn't realize that the Bible is not about works, but Grace. Its about the fact that we can never know what is good enough, and even if we could know how good is enough, we can never be good enough. That's why Jesus had to come and die; because he was the only one who could be good enough. I am ashamed to say that I did not have the presence of mind to present this to them. I continued listening, unsure of how to voice my own thoughts and beliefs.
If I could do it over, I would say that I agree with them that many of our churches have the wrong focus, that they are focused too much on whether someone has a Tattoo, a nose piercing or wears pants and not focused on the real issue loving one another. I also agree that most religions have similarities, I was amazed myself to find many similarities between Christianity and Hinduism, they were small but they were there. However, I do not believe that all religions are equal, I believe that there is one that is the truth and all others are forgeries. I believe that there is a God who though loving is also just, and righteous. That he gave us his truth first in the Hebrew Scriptures and the Jewish people,and later through the writings of the New Testament. I believe also that there is a Devil, who was once a holy angel was not satisfied with his place and sought to over throw God and become God himself. And since he could not do that he twists what God has said and turns them into half-truths to confuse and mislead people. I believe that there is a literal Heaven and a literal Hell and that those that do not except Jesus as the Son of God will one day die and spend eternity in Hell.
What I don't know is how to convince my friends of this truth, how I can show them that this is real? To be honest Christianity is all I've ever known, and while I am sure in my own heart that it is not "just the way I was raised" I don't know how to show that to others. I pray that I can show them Jesus Love working through my life and making me a better person than I was yesterday and I pray that God will be able to use even my failures to bring them to Himself.
