When Mary greeted Elizabeth, she was filled with the Holy Spirit. One of the central characteristics of the Kingdom Jesus inaugurated is that people would be immersed in the Holy Spirit. This Holy Spirit is not a sub-diety; He is the third person of the Trinity, three persons but one God. There are five biblical facts that substantiate the reality of the Trinity: 1.The Bible names that Father as God. 2.The Bible states that the Son is God. 3.The Bible also refers to the Holy Spirit as God. 4.The Father, Son and Spirit interact with one another. 5.The Bible makes it clear that there is only ONE God.
