DANIEL 2:33
 

That image or statue in Nebuchadnezzar's dream stood on iron legs with feet that were partially iron feet completed with clay. The budgeted iron completed its legs but could not complete its feet, and there was no other remaining metallic material that was available to complete the formation of the feet, and so clay was used to fill in the deficit. Either whoever estimated the size or volume of the four metals required to complete the statue underestimated it, or whoever built those metals into the statue mismanaged the available resources of metals, so that it could not complete the entire project as projected: and someone decided to use clay to compensate for the deficiency of metals before the full image of a man statue was built.
 

God only used a single rib of the man, and built a complete woman just from a rib that was not up to an arm's length; but the builders of that Statue had so much but could not finish it. Why?
 

[Luke 14:28-30] — "Which of you, wishing to build a tower, does not first sit down and count the cost to see if he has the resources to complete it? Otherwise, if he lays the foundation and is unable to finish the work, everyone who sees it will ridicule him, saying, ‘This man could not finish what he started to build.’"
 

I asked "Why" and you quoted "Luke 14:28-30;" I want to know why or how the Lord God Himself used just a man's rib to build a woman that was almost as large as the man, but the builders of the statue in Nebuchadnezzar's dream had so much gold, silver, bronze and iron, and yet the feet of the statue they built were where they hid their inadequacy of metals with clay to makeup.
 

This differentiates between "The Wisdom of God" as Master Builder and "The wisdom of men of this world."
 

*1* When men build image or glory of a man, their wisdom at best leads them to choose materials based on "Quality and Quantity." Mind you that's wisdom, but not the ultimate Wisdom.
 

*2* When God builds image or glory of a man, His Wisdom at least leads Him to choose materials based on "Life, Eternity and Purpose." God is not after Quality or Quantity, infact, God is not a professional Quantity Surveyor: If you ask God to estimate the quantity of materials required to build a structure, God may tell you just one small stone is enough to complete a mansion or a giant. I mean, there's a way God evaluates things differently from how "Professionals" in various fields would evaluate or value them.
 

So God is not after "Quantity or Quality" but after "Life, Eternity and Purpose" when selecting the materials to use for building. For example, that image in Nebuchadnezzar's dream had legs of Iron: and Iron is technically the strongest metal among the gold, silver, bronze/brass and clay. But clay is the weakest among them, unless burnt thoroughly or hardened. In the feet of that image, the strongest and the weakest materials, iron and clay, were used.
 

But God would rather use clay than use iron in building image of man. Infact, I have not seen or heard anything inside God's heaven is made of Iron: Iron just have no place for use inside heaven or spiritual things, except earthly or carnal things. It is forbidden to allow or raise anything iron on a Holy Altar of God even on earth according to "Deuteronomy 27:5." Heavenly or spiritual things work with Stones, Dust, Precious Stones and Crystals, not Iron. Perhaps the only use of Iron for someone from Heaven is the use of "Rod of Iron" to rule on earth.
 

Iron is highly strong and cannot easily be broken by some hard metals; and even iron coming from the south may not break iron coming from the north in equal size and momentum. As is written:
 

[Jeremiah 15:12] — "Shall iron break the northern iron and the steel?"
 

However, "Iron sharpens Iron" (Proverbs 27:17).
 

But understand that though tough substance may not easily break iron on earth, soft substance such as air and water do have ways of rusting or corrupting iron, which means they break iron that harder ones could not break with time.
 

I told you God is not after Quality or Quantity unlike Structural Engineers; rather God is after Life, Eternity and Purpose. Iron does not fit any of these requirements of God in selection of materials for His Building.
 

*** Life here means the Substance or Stone God will use to build must be able to grow, live and move. Hence, "Living Stone." The "Growth or Growing" ability of the Substance or Stone is what replaces "Quantity" in God's estimation. One reason God could choose a small stone for gigantic project or a rib for the image and glory of man called woman, is because of its living abilities for growth, development and transformation. Not in quantity, but in growth: In the latter part of that Nebuchadnezzar's dream, a small Stone was cut out without hand just as a rib was taken from Adam, and that Stone struck the Image of men by those feet that had both iron and clay, crushing the entire statue: and then suddenly that small stone began to grow, expand, and transform into a great Mountain that filled the earth.
 

Where those metals or iron finished was where they stop in quantity or size; and therefore, they used clay to compensate for the shortage because those metals could not grow or multiply themselves to increase or reproduce. But see how God built our Body in ways that our cells can both grow and multiply themselves. Even so, the Body of Christ has both members fitly joined together, connected to the Head, and all grows in all things to Him.
 

[Ephesians 4:15-16] — "But speaking the truth in love, may grow up into Him in all things, for He is the head, I mean Christ: From Him the whole Body fitly joined together and compacted by that which every joint supplies, according to the effectual working in the measure of every part, makes grow of the body to the building (edifying) of herself in love."
 

Not a physical church building that cannot grow beyond the size those who built it left or stopped building it; but a spiritual church where even when the builders stop building it, the church will still be growing by itself or edify itself without the builders; and keep growing forever like a Plant that never stops growing. And it will come to pass that not even the builders can take the credit they built the Temple or Church because the Church would have built Herself far above what the builders thought or imagined when they began building till they stopped building Her. So they cannot take the glory for building the Church, but only the honor for building Her Foundation: for all they ever built will best be described as foundation relatively to how much she grew Herself and became; and even the Lord Jesus Christ Himself that will build His Church on this Rock, will just become the Chief Corner Stone among Foundation Builders, for She built Herself.
 

[Ephesians 2:20-22] — "And are built on the foundation of the apostles and prophets, Jesus Christ Himself being the Chief Corner Stone; In whom all the building fitly framed together grows to an holy temple in the Lord: In whom you also are built together for an habitation of God through the Spirit."
 

*** Eternity and Purpose: These replace Quality in God's selection of materials to use in building. As a result, whatever God builds endures forever (eternal) having both time and purpose for everything in it. As it is written,
 

[Ecclesiastes 3:14] — "I know that, whatever God does, it shall be for ever: nothing can be put to it, nor any thing taken from it: and God does it, that men should fear before him."
 

Men can do something and it becomes temporary or pass away, but when God does something it is eternal or forever. People may think God is slow, but He knows the implications of His actions and how whatever He does are not something that can easily be added or subtracted (edited) like men find their works on earth during their times and seasons.

If you understand that eternity is a form of time, you understand Iron cannot stand the test of Time though Iron stands the test of Strength.

At the feet, the Iron members had begun rusting and changing into clay because Iron does not stand test of Time with all its strength. The Feet represent "Endtimes;" and the Iron could not endure through the endtimes or last days. But there are Feet that will do exploits in the last days, including the Feet of the Lord Jesus under whom all His Enemies are made His Footstool in subjection and the Endtimes Christians/Church who are the representative of all who have gone before them on earth. The Endtimes or Last days Christians are His Feet or our Feet.
 

[Romans 16:20] — "And the God of peace shall bruise Satan under your feet shortly. The grace of our Lord Jesus Christ be with you. Amen."
