Just the opposite. Jesus sets us free the penalty of sin.

(John 8:34-36 NIV) Jesus replied, "I tell you the truth, everyone who sins is a slave to sin. {35} Now a slave has no permanent place in the family, but a son belongs to it forever. {36} So if the Son sets you free, you will be free indeed.

Blasphemy is for fools. You'll just make your eternal punishment greater. You can laugh now. We'll laugh together in a hundred years if you still want to.
