Usable Material

God is a spirit and divine in His nature. The church of God came down from heaven, and is a spiritual organism. God can only build this organism with individuals with the spirit of God or divine nature, hence the inception of the church upon the receiving of the Holy Ghost in Acts 2.  If a church begins to exercise and promote people, purely out of what they can offer in terms of their natural ability and expertise, and not based upon their spiritual substance, they become an earthly organization. Anything external, such as: physical appearance, name, heritage, natural ability, socioeconomic status, relationships, etc. do not make you usable material in God's church, but rather the quality of your spiritual life.
