Pneumatology is the area of Christianity that is concerned with the doctrine of the Holy Spirit, which is the third person of the Holy Trinity (Father, Son, and Holy Spirit). There are many aspects of the the Holy Spirit. First of all, the Holy Spirit is just as much a person as the Father and Son are. In addition, just like the Father and Son, the Holy Spirit has a personality that is capable of many actions and emotions such as loving, praying, grieving, punishing, etc. In fact, the Holy Spirit is the aspect of God that actually influences our emotions and will. Another aspect of the Holy Spirit is that He is omnipresent, omnipotent, and omniscient. This means that He is always present, all-powerful, and knows all. The Holy Spirit is also eternal, never ending and is everywhere.
