211. "'I urge you to buy from Me gold refined in the fire, that you may be enriched.'" (3:18) This symbolizes an admonition to acquire for themselves the goodness of love from the Lord by means of the Word, in order to become wise.

That is because to buy means, symbolically, to acquire for oneself. "From Me" symbolically means, from the Lord by means of the Word. Gold symbolizes goodness, and gold refined in the fire, the goodness of celestial love. And to be enriched means, symbolically, to understand and become wise.

Gold symbolizes goodness because metals in their hierarchy symbolize qualities connected with goodness and truth. Gold symbolizes celestial and spiritual goodness; silver, the truth accompanying those good qualities; bronze, natural goodness; and iron, natural truth.

These are the symbolic meanings of the metals of which Nebuchadnezzar's statue consisted, the head of which was gold, the breast and arms silver, the belly and thighs bronze, the legs iron, and the feet partly iron and partly clay (Daniel 2:32-33). These metals represented the successive states of the church in respect to the goodness of its love and the truth of its wisdom.

Because the states of the church followed in succession in this way, the ancients therefore gave the ages these same names, calling them the golden age, the silver age, the bronze age, and the iron age. And by the golden age they meant the first period, when the goodness of celestial love reigned. Celestial love is love toward the Lord received from the Lord. From this love they then had their wisdom.

A "reward" in the Bible represents something that brings people together, or brings spiritual states together, and binds them. In the Bible, of course -- especially the New Testament -- we're told repeatedly to do what is good and right "without thought of reward." That's because removing the idea of a natural reward lets us be aware of spiritual rewards, which are actually intrinsic to the good that's being done. On a relatively low level, we feel delight in doing something nice and useful for someone else; that delight is a reward. The love that can exist between partners in a committed, loving marriage is a reward. The delight we feel when we truly want what is good and know how to create it is a reward. And ultimately, our conjunction with the Lord and the delight of His love and salvation is the deepest reward of all. These are the things meant when the Bible speaks of "rewards.
