If you're looking for a real, promising answer, I recommend you go to this website called JW.org
Many people have various opinions on this matter but if you read in the Bible about what Jesus did as a human on this earth, he went around preaching and telling of the good news about God and giving the people hope for the future. If you read the the accounts of Matthew, Mark, Luke and John, they all tell the same thing just in different formats of wording. I really hope you find this interesting. If you ever have any questions, feel free to contact any one of Jehovah's Witnesses on the website I mentioned above and I'm sure they would be happy to answer your questions!
