One of the most fascinating, yet mysterious, teachings of the Bible is the Mystical Union. The term Mystical Union describes God living within you. The Bible speaks about all three Persons of the Holy Trinity living and dwelling within you in a special and unique way[1]. One of those places that teaches this doctrine is the book of Ephesians.

[1] The Bible speaks about each Person of the Holy Trinity living within you, for example in John 14:23 (Father/Son) and 1 Corinthians 6:19 (Holy Spirit). One fascinating thing about this Ephesians 3:16-17 passage is the Trinitarian nature of the prayer; that the Holy Trinity takes a personal interest in you and your Christian faith (Know and grasp Christ’s love) and life (love and care for others); so that you ultimately are filled with the Lord and the holy things of His Kingdom!
