Is unbelief a sin?
I believe it is.
God commands all men to repent and believe.
If God commands something and we do not do it, it is sin.

it depends on how the term "unbelief" is understood according to the corresponding context, the unbelief of a worshiper is a sin if it consists in some misbelief, in all other cases the unbelief is not a sin
Mark 6:1-6 "And he went out from thence, and came into his own country; and his disciples follow him. And when the sabbath day was come, he began to teach in the synagogue: and many hearing him were astonished, saying, From whence hath this man these things? and what wisdom is this which is given unto him, that even such mighty works are wrought by his hands? Is not this the carpenter, the son of Mary, the brother of James, and Joses, and of Juda, and Simon? and are not his sisters here with us? And they were offended at him. But Jesus, said unto them, A prophet is not without honour, but in his own country, and among his own kin, and in his own house. And he could there do no mighty work, save that he laid his hands upon a few sick folk, and healed them. And he marvelled because of their unbelief. And he went round about the villages, teaching.",
Romans 3:1-4 "What advantage then hath the Jew(i.e. the worshiper)? or what profit is there of circumcision(i.e. of faith)? Much every way: chiefly, because that unto them were committed the oracles of God(i.e. to them is given the chance to be spiritual servants of God). For what if some did not believe(also: what if some are not believers/worhsipers)? shall their unbelief make the faith of God without effect? God forbid: yea, let God be true, but every man a liar(i.e. every human incompetent compared to Him); as it is written, That thou mightest be justified in thy sayings, and mightest overcome when thou art judged(i.e. when You do Your work on the overall salvation in Jesus Christ)."
