Pdfangus, you bring up the contention that exist between the different religions over who's God is the true God. Also you bring up the possibility that they all worship the same God only in different ways and God has revealed Himself to the world through different men. We also have to take into consideration the views of atheist and agnostic's. Your real question is can we know the truth and who is right or could they all be right.
If the atheist says when we die its the end and the Hindu and Buddhist belive in reincarnation. The Muslim believes he will be in some level of paradise but not actually with Allah himself and the Christian believes he will be in heaven with God they can't all be right. Your right, there are many religions and many gods that offer peace. The one thing seems blaringly obvious to me is that there is no way for them all to be right. If the atheist is right then all of the religions are wrong. If only one of the religions is right then the atheist is wrong but so are all the other religions. For us to know who is right we must know who has the truth because only the truth is right.
So who has the truth is the real question, because whoever has the truth is right.
An agnostic does not believe we can know the truth so I dismiss him. The atheist believes in happenstance. We are the product of an explosion that produced a star with a planet in just the right orbit for life to just begin from a random chemical reaction. I can't even start to get my mind to comprehend that. I'm sorry but I just don't have that much faith in explosions.
Of the major religions they can't all have the truth because they teach different things concerning God, mankind and the afterlife. Since they can't all be right only the one with the truth is for me but which one has the truth? If we look closely we'll find that most of them are really not all that different at all. Of 31 major religions in the world most of them teach that peace with god is achieved by being good and doing good things. As a matter of fact they all teach this except one. The problem is that they all have so many different opinions of what being good is. My problem is I don't see people as being good. Sure people do lots of good things and I like to think for the most part we try to live good lives. Yet even the best of us lie, cheat, steal, hate, want what others have and I could go on. I think you have to agree we are a pretty bad lot. So being good isn't going to get it done for me.
So where does that leave me? It leaves me with that one religion that doesn't teach that I'll find eternal peace by being good, Christianity. So what does it have to offer me? It tells me I'm not good, it tells me I can't possibly earn my eternal life by being good or doing good deeds. I know from my own life that's the truth. It doesn't have a list of rules that I have to live by to get eternal life although most people thinks it does. It does have a book of principles that will make life better if we apply them but its not a book of laws that we must abide by. We are given ten commandments although it acknowledges that we are not capable of keeping them because by our nature we are rebellious. It even explains to me why I'm not capable of being good enough to earn eternal life.
So what exactly does Christianity offer me? Well it offers me more than just a dry religion. It offers me a God who became one of us and lived as one of us so that He could reveal Himself to us. He also became one of us so that He could know what It's like to be one of us so He could understand us better. He faced everything that any of us have ever faced or ever will face. He was tempted just like we are tempted only He over came temptation proving that He and He alone is righteous. Then He gave His life for us so that through His righteousness I can be forgiven for being bad and have peace and eternal life through His righteousness.
So I choose Jesus and by putting my faith in Him I have a relationship with God that goes way beyond an empty religion.
