Why would anyone not want to accept Jesus as their savior?

One of Jesus' claims was that he had the authority to forgive sins and that simply by believing in him we could have that forgiveness. There is a lot of peace in knowing that all my sins are forgiven . To obtain this you need only to confess Jesus as your Lord and savior. You don't have to follow a whole lot of rules or do a lot of works. Salvation is by grace (a free gift) and by believing in the completed work of Jesus of Nazareth, the Messiah, who rode on a donkey into Jerusalem exactly on the day prophesied by Daniel.
