Edification/Holiness
This is the primary goal of the church. All the other seventeen elements are summarized in this one aspect, which is God's desire for us to be like Him. Because we are bought with a price, we have no right to live for ourselves but for the glory of Christ; which is not a killjoy but a higher pleasure. (Here is an article from Desiring God: http://www.desiringgod.org/blog/posts/the-beauty-of-holiness-and-the-miracle-of-sanctification)
In God's providence, He has brought us together as Grace Covenant Church to be sanctified by the truth so that we would be a testimony to the world of the Trinitarian arrival of Jesus Christ and His Kingdom. The Spirit intends for us to build each other up in the word of God, so that we could be used in His service. He moved Paul to express his prayers to the Ephesians about His expectation of churches everywhere of all ages to grow in the grace and the knowledge of our Lord and Savior Jesus Christ. Let's expound on them and see if we could get some practical applications for our Church Community. (Eph 1:16-23, 3:14-21)
