God’s presence within our spiritual being is the basis not only for communion with Him, but is also the foundation for ultimately fulfilling the purpose for which we were created in at least three significant ways:

First, only those who are alive in their spirit are capable of worshiping God in the way He desires.(1 Corinthians 2:10 & 12)   

Second, only those spiritually alive can receive the impartation of God’s truth. For only through our spirit can we gain knowledge of the truth that He otherwise leaves shrouded in mystery.(Romans 12:4-8, 1 Corinthians12:7-11, Ephesians 4:11)

Third, God reaches through His children to draw a hurting and dying world to Himself. We actually become His hands and feet as He manifests Himself to the lost around us. And our job here on earth encompasses not only reaching the lost, but also being used to build up Christ’s body, the Church. But in no way are we capable of handling this job in our own strength. We can do it only by the gifts and ministries He gives to each one of us individually.(Romans 5:12) Our spirit is the port of entry, the staging area, and the jumping-off place of these gifts.
