- Another Answer
Are you asking if Jesus is real, if Jesus is alive, if Jesus is in Heaven, if Jesus is who others say he is. These questions are questions about the Jesus of Faith and are sometimes messed up with the Jesus of History, who walked on earth.
First have faith, then comes experience. Faith is personal, faith is a relationship with a living person, albeit, not visible in this dimension. Seek, and you will find your answers to your questions. Remember, Jesus taught that the Kingdom of God is within you. Seek your answers within you.
- The First Answer
Non-unitarian Christians believe that Jesus is the Son of God and also the incarnation of God (see Wikipedia:Trinity).
Other religions reject the claim that Jesus was a Messiah or believe he was merely a prophet.
