Many Christians believe that Jesus is God (it's just a matter of realizing how widespread trinitarianism is, for example). However, there are Christians that go one step further and act on this belief, treating Jesus for all practical purposes as God almighty. They pray to Jesus, they talk about Jesus all the time, and they even worship Him as God (for some good illustrative examples, please see this and this).
Likewise, there are Christians who do pretty much the same with the Holy Spirit. A very good example is Benny Hinn's best-selling book Good Morning, Holy Spirit, which has been read and cherished by thousands, if not millions of Christians around the world. In this video clip you can see Benny Hinn leading a whole stadium to worship the Holy Spirit.
Question: According to Biblical Unitarians: Does worshiping either Jesus or the Holy Spirit as God entail committing the sin of idolatry? When Christians worship Jesus or the Holy Spirit as God, are they sinning? If the answer is yes, then what happens to those Christians who have systematically committed this sin throughout their lives and die never repenting? Will they go to Hell as unrepentant idolaters, or does the answer depend on other conditions?
Answering to the comments: why would idolaters go to Hell? 1 Cor 6:9: Or do you not know that wrongdoers will not inherit the kingdom of God? Do not be deceived: Neither the sexually immoral nor idolaters nor adulterers nor men who have sex with men
