Under the Old Covenant the temple, and the tabernacle before it, served to symbolize God’s presence among the people. It was the focus of their worship. But the need for a separate physical structure disappeared at Pentecost when God’s Spirit took up his dwelling with a living temple made up of all believers.
I keep asking that the God of our Lord Jesus Christ, the glorious Father, may give you the Spirit of wisdom and revelation, so that you may know him better. I pray that the eyes of your heart may be enlightened in order that you may know the hope to which he has called you, the riches of his glorious inheritance in his holy people, and his incomparably great power for us who believe. - Ephesians 1:17-19 NIV
All Scripture is God-breathed and is useful for teaching, rebuking, correcting and training in righteousness, so that the servant of God may be thoroughly equipped for every good work. - 2 Timothy 3:16-17 NIV
