the Son of Man has authority on earth to forgive sins

He says the son of man has the authority to forgive sins. If he is trying to explain that he is god, he is doing a terrible job. To me it seems like he is saying “you think only god can forgive sins, I’ll show you you’re wrong”

If someone were to wrong me, would my child be able to forgive them? Nope.

You’re saying that your omnipotent god can’t authorize someone to forgive sins on its behalf?
