Amen, Dr. E. I would carry this one step further. Every Christian, no matter how large or small, is important to the fabric of God's tapestry. Christ is the cornerstone and each of us is a block within the structure of the church. Every one of us is important and divinely joined to Christ's Spirit. We should never think that one of us didn't need to exist. That is not how God views it.
I would recommend Joseph Philpot's article, Blessings Imputed. Here is a small quote from his argument:
1. Every soul, then, that ever had, has now, or ever will have a standing in Christ, had this standing in Him from all eternity. Just in the same way as the vine, according to the Lord's own figure, puts forth the branches out of the stem; not a single branch comes out of the stock but what previously was in the stock--so, not a single soul comes manifestatively into spiritual existence which had not first an invisible and eternal union with the Son of God. This eternal, immanent, and invisible union with the Person of Christ, God blessed his people with before all worlds, by his eternal purpose, and according to his own eternal counsel.
2. Now, out of this eternal and immanent union springs the second union that we have spoken of, which is a time union--a union in grace--a vital union between a living soul and a living Head. Until the Lord quickens elect vessels of mercy they have eternal union, but they have not time union. Their eternal union never can be altered--that never can be dissolved--that accompanies them all through their unregenerate state--but their vital, spiritual, and experimental union takes place in time, through the teaching, and under the operations of the blessed Spirit.
Importance doesn't approach necessity. God "needs" to exist, I don't. God did not create us out of necessity, God is not contingent upon our existence.
