The indwelling of the Holy Spirit is the action by which God takes up permanent residence in the body of a believer in Jesus Christ. In the Old Testament, the Spirit would come and go from the saints, empowering them for service but not necessarily remaining with them (see Judges 15:14; 1 Chronicles 12:18; Psalm 51:11; Ezekiel 11:5). Jesus revealed to His disciples the new role the Spirit of Truth would play in their lives: “He lives with you and will be in you” (John 14:17). The apostle Paul wrote, “Do you not know that your bodies are temples of the Holy Spirit, who is in you, whom you have received from God? You are not your own; you were bought at a price. Therefore honor God with your bodies” (1 Corinthians 6:19–20).
