How about those who are added to the foundation of God's building (Jesus Christ) being the 'silver and gold and precious jewels', and the 'spiritual truths taught by the Spirit' being the tools the other workers used to place them there? Wouldn't that be consistent with scripture?
"19So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, 20having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone,21in whom the whole building, being fitted together, is growing into a holy temple in the Lord, 22in whom you also are being built together into a dwelling of God in the Spirit." (Ephesians 2:19-22 NASB italics in original, bold)
"4And coming to Him as to a living stone which has been rejected by men, but is choice and precious in the sight of God, 5you also, as living stones, are being built up as a spiritual house for a holy priesthood, to offer up spiritual sacrifices acceptable to God through Jesus Christ." (1 Peter 1:4-5 NASB bold mine)
"the holy city, Jerusalem, coming down out of heaven from God, 11having the glory of God. Her brilliance was like a very costly stone, as a stone of crystal-clear jasper." (Revelation 20:10-11 NASB bold mine)
The precious materials built onto the foundation of Christ and the Apostles and Prophets, able to withstand fire (unlike hay, wood, and stubble), are believers.
Excellent parallel verse. I will add this to my learning.
And may I add this:
" 11“You have conceived chaff, you will give birth to stubble;
My breath will consume you like a fire.
12“The peoples will be burned to lime,
Like cut thorns which are burned in the fire."
(Isaiah 33:11-12 NASB)
It's clear that those in the kingdom who are false, being only made up of hay, wood, and stubble, will be burned away in the Judgment because they are made of that which will not be able to withstand the coming fires of Judgment when the kingdom is purged of everything false and perishable.
We as workers in the building of God should be careful how we build so that who we build onto the household of God are real and will be able to withstand the coming Judgment and not be purged away by fire. If we do that they will be our reward in heaven over whom we will rejoice, and they over us: "we are your reason to be proud as you also are ours, in the day of our Lord Jesus.(2 Corinthians 1:14 NASB).
But if who we minister to doesn't make it through the fire at the end, who will be there for us to exult in? "19For who is our hope or joy or crown of exultation? Is it not even you, in the presence of our Lord Jesus at His coming? 20For you are our glory and joy." (1 Thessalonians 2:19-20 NASB)
So, let's be careful how we build folks, so we won't lose our reward at the Judgment. We ourselves will be saved, but we will have nothing to show for our labor in the kingdom and will have run our race in vain because they did not make it: "14Do all things without grumbling or disputing; 15so that you will prove yourselves to be blameless and innocent, children of God above reproach in the midst of a crooked and perverse generation, among whom you appear as lights in the world, 16holding fast the word of life, so that in the day of Christ I will have reason to glory because I did not run in vain nor toil in vain." (Philippians 2:14-16 NASB).
What Paul is talking about is the foundation of the inner house, the house of the inner man; the building that the inner man builds, that being Christ in spirit; the house that can not be seen yet. We know that because he uses the language of the proverbs, gold and silver and precious stones to represent knowledge and understanding and wisdom. He is talking about the building that is spirit, the building not built with hands.
2 Corinthians 5:1
For we know that if the earthly tent we live in is destroyed, we have a building from God, a house not made with hands, eternal in the heavens.
