The word "spirit" can often be confusing. Mainly because it can be used of a person, of the Holy Spirit (Third person of the Trinity) and of angelic and demonic creatures (evil spirits). For example when Jesus dies, he gives up his "spirit." This is not talking about the Holy Spirit or an angel or demon. This is talking about the human spirit (if someone wants to ask a question on the Holy Spirit, I am happy to answer that too). There are many places that talk of the human spirit (a few examples, Rom. 1:9, 1 Cor. 5:5, 1 Cor 7:34, 2 Cor 7:13).
