Jesus is a Sun; The Sun! And if we come to Him before The Day of Judgment, “The Day of Vengeance of our God,” we will not be smitten of Him. But to those who refuse Jesus, to give up their lives and follow Him, they will be scorched by the judgment of God.
Though not appointed for everyone, this scorching is shown most literally in Revelation, to those found dwelling upon the earth during the last judgments of God. “that great day of God Almighty.”
"And the fourth angel poured out his bowl upon the sun; and power was given unto him to scorch men with fire. And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give Him glory." [Rev 16:8-9]
The Sun will not smite us; however, those who refuse will be scorched by Christ. For “The Father judgeth no man, but hath committed all judgment unto the Son.” [Jn 5:22]
This sun-related judgment is shown to us in Hosea. The LORD says to Israel through Hosea that He is going to judge them for their idolatry. They refused Him and wouldn’t return to Him and so God says,
"Therefore they shall be as the morning cloud, and as the early dew that passeth away, as the chaff that is driven with the whirlwind out of the floor, and as the smoke out of the chimney." [Hos 13:3]
Notice that all these idioms of judgment are related to the sun. The sun burns away the thin, morning clouds; it evaporates the dew; and the sun indirectly causes wind through uneven heat distribution of the air, thus creating wind to drive away smoke and chaff. Through these idioms of judgment, we are reminded that Jesus, the Sun of Righteousness, will be a Scorching Sun to those who refuse Him.
"Kiss the son, lest He be angry, and ye perish from the way, when His wrath is kindled but a little. Blessed are all they that put their trust in Him." [Psa 2:12]
There are two options: come to Christ and be looked upon with grace, mercy, and peace, delighted with pleasantness in the presence of The Sun. Or refuse Him and be scorched by His burning presence. The sun can be good or bad, pleasant or unpleasant. The sun is enjoyable, but if it is extremely hot, it can become the opposite. So it is with Jesus Christ.
This is also shown to us in the gospels. Jesus said that those who come to Him now, falling upon Him in submission, will be broken. But those who wait until Jesus falls upon them in judgment will be ground to powder.
"And whosoever shall fall on this stone shall be broken: but on whomsoever it shall fall, it will grind him to powder." [Mt 21:44]
The promise remains: come to Christ and be saved. Isaiah says,
"They shall not hunger nor thirst; neither shall the heat nor sun smite them: for he that hath mercy on them shall lead them, even by the springs of water shall He guide them." [Isa 49:10]
And the promise to the rejecters of Christ remains as well,
"Out of Zion, the perfection of beauty, God hath shined. Our God shall come, and shall not keep silence: a fire shall devour before him, and it shall be very tempestuous round about him." [Psa 50:2-3] "A fire goeth before him, and burneth up his enemies round about." [Psa 97:3]
Jesus is the better option. “For the LORD God is a sun and shield: the LORD will give grace and glory: no good thing will he withhold from them that walk uprightly.” [Psa 84:11]
