The order of our ardor
"And they said one to another, Did not our heart burn within us, while He talked with us by the way, and while He opened to us the scriptures?" (Luke 24:32)
Dig deep enough and you'll find it. I don't believe God's ever silent but ever communicating. The above verse is two followers of Christ who had seen all their hopes dashed with His death. They were walking to Emmaus, a village seven and a half miles from Jerusalem and were accompanied by a stranger who happened to be Jesus. I know it says "their eyes were holden that they should not know Him." (24:16) but something tells me that deep down, they did. Their hearts witnessed to the truth of this stranger, who, it says "expounded unto them in all the scriptures the things concerning Himself." (24:27) But it wasn't until afterward, after they had shared a meal that "their eyes were opened, and they knew Him" (24:30). It then says that "He vanished out of their sight." Think about the order in which things happened. These two men were going to Emmaus, commiserating among themselves, thinking they knew how it ended--and that it had indeed ended. But Jesus, ever the Good Shepherd, shows up and gently stokes the pilot light on their insides. After He disappeared from their communion, the two men hurried back to Jerusalem--to the fold. I'd wager to say it was a layer or two of unbelief that kept His identity hid from them. As an aside, is it the layers of unbelief in our lives that keep us from seeing God walking right by us in our everyday lives? Food for thought. At Jerusalem with the rest of the disciples, Jesus proceeds to expound a bit more on His coming and the scriptures that foretold it. He then adds "but tarry ye in the city of Jerusalem, until ye be endued with power from on high." (24:49)
"I have set the Lord always before me: because He is at my right hand, I shall not be moved." (Psalm 16:8)
In Thermodynamics it refers to air being heated by the sun. In Chemistry, it's the so-named process of heat transfer between molecules. In other words, diabatic heating is getting warmer through heat proximity. Perhaps this is why Jesus instructed the disciples to "tarry in the city of Jerusalem". To stay near the source, the fire. The second chapter of Acts (written by Luke, his Gospel and Acts were originally one book) opens on the day of Pentecost. Verse two says "they were all with one accord in one place". It would seem some conditions had to have been met before the "power from on high" was released. A spiritual "heat transfer" as it were. Jesus swept everyone back to Jerusalem and after they had all ironed out their differences (There seems to have been a lot of doubt and griping among the disciples, oh well.) "there appeared unto them cloven tongues like as of fire, and it sat upon each of them." (2:3) God is moving by His Spirit. He commemorates the Jewish celebration of Pentecost with a fresh outpouring of the Holy Spirit. Something that we partake in even today. Jesus started the fire and it will slowly die down unless we stay near to Him. After the crowd saw what happened to those in the upper room--and began to doubt in spite of it (see2:7-13)--Peter does the same as Jesus. He cites Joel and also David to keep the dream (and the fire) alive. He says "For David speaketh concerning Him, I foresaw the Lord always before my face, for He is on my right hand, that I should not be moved." (2:25) God poured the Holy Spirit out upon the Church and ignited their individual pilot lights (you and I have them) into a conflagrated and communal bonfire. To where anything trying to snuff or damper, evaporates instead. This is a good thing.
"He (David) seeing this before spake of the resurrection of Christ, that His soul was not left in hell, neither His flesh did see corruption." (2:30)
"Then was Nebuchadnezzar was full of fury, and the form of his visage was changed against Shadrach, Meshach, and Abednego: therefore he spake, and commanded that they should heat the furnace one seven times more than it was wont to be heated. Then Nebuchadnezzar the king was astonied, and rose up in haste, and spake, and said unto his counsellors, Did not we cast three men bound into the fire? They answered and said unto the king, True, O king. He answered and said, Lo, I see four men loose, walking in the midst of the fire, and they have no hurt; and the fourth is like the Son of God." (Daniel 3:19, 24-25)
Incalescent simply means "to increase in heat". All Global Warming aside, I find it's the natural order of things. God is hot, how else can I say it? And the closer you get to Him, the more the heat gets turned up. While Peter (quoting David) says that "His soul was not left in hell", there may be times where, like the three men spoken of in the above passage, you might have to wander around in the fire. No matter. It might be anachronistic, but Jesus was there with them and He's in the fire with you. Let it get hotter, let it incalesce. There's nothing hotter than Him. If you can't stand the heat, then ask Him to show you why--to open your eyes. With Him by your side, you won't "smell of fire" (Daniel 3:27). And you'll be qualified, as is He, to lead people through hell, and out.
"His head and his hairs were white like wool, as white as snow; and His eyes were as a flame of fire." (Revelation 1:14)
