We learn in 1 John 5:7 that the trinity is what God is. God is three in one, Father, Son and Holy Ghost. I believe when we see God it will be just 1 being in Heaven but he expresses Himself as a Father, Son and Holy Spirit. The Holy Spirit can dwell in us and does when we truly accept Jesus. 1 John 5:7 says, “For there are three that bear record in heaven, the Father, the Word, and the Holy Ghost: and these three are one.” I am thankful to God for the comfort and gift of the Holy Ghost. Amen
