Before beginning a project a good builder will make a blueprint to help him know what the end result is to look like. That will let him know steps to take, a plan needed to get there.
God has provided a blueprint for the growth, or building up, of His Church in His Word.
Scripture Passages on God's Design for Body Life:
The following passages show us God's Blueprint Design for Building the Church. If we want a healthy, growing Church, we must function according to His intent as laid out in His Word.
Ephesians 4:11-16 - Goals
1 Corinthians 12:14-26 - Structure
Romans 12:1-21 - Requisites
The Body Life Ministry Manual provides more input into each of these passages as well as some helps for further reflection.
