I am not a Muslim but I am interested in learning about it. I have been raised a Christian, as far as Christianity being the absolute truth, I could not say that to someone with absolute conviction, because of the fact that the Bible which is supposed to be the word of God, contradicts itself. For example the Bible says in the old Testament that God is a jealous God and not to worship anyone or anything except him, then the New Testament says that we have to believe in Jesus, this is confusing. Then in the New Testament Jesus says that to follow him, one must give up all his possessions including those he loves. Later the New Testament it says that all we need to do go to heaven and be forever forgiven of our sins is believe that Jesus was God, and that he died for our sins. Once we have confessed this with our lips and asked God for forgiveness, we are forever saved from our sins.
You have to admit these mixed messages can be confusing. In everyday life, I have found that the truth fits easily where it belongs. If you are confused you don't have the truth yet. That's my experience.
I am reading the Quran and have only gotten about a 100 pages into it so far, so I can't say that its message is not confusing or if it makes perfect sense. The first part set right with me though because ever since I was a little girl and I've prayed, I have always addressed my prayers to God. I have never felt comfortable addressing my prayers to Jesus, or saying Thank You Jesus, I always have just naturally addressed prayers for guidance to God, and gave thanks to God. I do believe in Jesus' teachings, I believe he was the most perfect person to ever walk the earth and that he taught the truth in his words and his actions, we should follow his teachings and live by his example, but I'm uncomfortable with calling him God, because I'm confused by the mixed messages from the Old Testament about there being only one God. Why did Jesus' name get changed from Yeshua? Why do Catholics who believe in Christ too, have more books in their Bible? Maybe over time the Truth in the Bible has become distorted trough interpretations, human error, and human intentions. The 100 pages that i have read in the Quran has actually clarified some things that I have questioned in the past from the Bible. Because the message of the Quran was given to only one prophet and not several, it's possible its a more absolute truth.
That's all. I apologize if I'm too wordy, I think as I write sometimes and tend to ramble.
