Religions, and such............

Is it ok to question Christianity? Is it ok to think that another religion might have some truth to them? What makes Christianity so right? I truly believe that Jesus died on the cross for my sins and was resurrected. I believe that Jesus is the way the truth and the life. (John 14:6) but i can not honestly say that another religion is wrong. Saying that Muslims, and Jews, and many other religions are wrong is not my call, i am not God. I am still going to share with them the good news of Jesus Christ, but i do not want to tell them that their faith is wrong and mine is right.
Many people may disagree with me on this one and i am fine with that, because i have checked out other religions for myself and i can tell you that before you judge a religion check them out yourself. I think that you too will find things out that will make you think.
Now i am not promoting another religion, but i think it is good as Christians to accept all people no matter race or religion. I think that Christians have a bad name because so many judge other religions so poorly. I hate to say this but when you look at other religions they seem to practice what they preach more so then today's Christians. I feel as if for some Christ is just a symbol of their religion and not a person they worship and have a relationship with. I hate the saying, "I am a Christian, but i don't practice". Thats is the stupidest thing to say. Why be something your not?
So in clearing this all up i Love Jesus Christ and want the whole word to know what it feels like to know that there is a spot in Heaven waiting for them. But i do not want to ignore what they have to say, and i want to try and see where they are coming from and why they believe what they believe.
