The New Testament tells us that as saved ones we have been regenerated in our spirit and that from the time we were saved, God has been edifying and building up our spirit. Ephesians 2:22 clearly reveals that our spirit is God's dwelling place in us. Hence, to build up our spirit, the individual spirit, is to build up God's dwelling place, God's temple. On the other hand, the church is also God's house and God's temple. But how do we build up the church? It is through all the saved ones encouraging one another and functioning in mutuality according to their fellowship with the Lord and the experiences of life they have had with the Lord in their spirit. The Body of Christ is built up through the spiritual development of all the members.
