Is accepting Jesus as messiah a sin?

It seems to me, that to accept Jesus as our messiah or scapegoat, means abdication our responsibility for our sins and placing it on the messiah or scapegoat.

I think that to use a scapegoat is a sin.

If you are religious, is this the sin that you think you did to deserve hell? If not, what is it that causes you to sin to be saved?
