Brass we learned was the symbol of the satisfaction of G-d’s judgement. Yeshua was the satisfaction of G-d’s judgement. The fire symbolized the presence of G-d.

Messianic Jews (Hebrews) {12:29} For our Gd is a consuming fire.

These three elements combined; the Acacia wood, the brass and the fire all represented Yeshua. He was incorruptible (the Torah in the flesh). He was the satisfaction of G-d’s judgement and He was G-d incarnate. To allow the fire to go out would break the continuity of the symbolism. Though they were able to do continuous sacrifices on the altar, Yeshua can be offered up only once. Israel needed to carry this symbolism with them wherever they went. They need a constant reminder never to let the fire of G-d’s presence out of their lives. This fire has ultimately found it’s resting place in us. We, are the Temple of G-d, and the fire of His presence now burns in us. Therefore we too must not allow our fire to go out. That is what Shaul (Paul) is telling us in:

Messianic Jews (Hebrews) {6:4} For it is impossible for those who were once enlightened, and have tasted of the heavenly gift, and were made partakers of the Holy Ghost, {6:5} And have tasted the good word of G-d, and the powers of the world to come, {6:6} If they shall fall away, to renew them again unto repentance; seeing they crucify to themselves the Son of G-d afresh, and put him to an open shame.

If we allow the flame to go out in our lives, as was the case for the mitzbeach, it cannot be lit afresh.
