1. Whence this mercy and comfort shall flow to them: To you that fear my name shall the Sun of righteousness arise, with healing in his wings. The day that comes, as it will be a stormy day to the wicked, a day in which God will rain upon them fire and brimstone, and a horrible tempest, as he did on Sodom (Ps. xi. 6), a day of clouds and thick darkness (Amos v. 18, 20), so it will be a fair and bright day to those who fear God, and reviving as the rising sun is to the earth; and particular notice is taken of the rising of the sun upon Zoar when that was mercifully distinguished from the cities of the plain, which the fire consumed; see Gen. xix. 23. So to those that fear God is comfort spoken. When the hearts of others fail for fear let them lift up their heads for joy, for their redemption draws nigh, Luke xxi. 28. But by the Sun of righteousness here we are certainly to understand Jesus Christ, who would undertake to secure the believing remnant, in the day of the general destruction of the Jews, from falling with the rest, and to comfort them in that day of distress and perplexity with his consolations; he directed those that were in Judea to flee to the mountains (Matt. xxiv. 16), and they did so, and were all safe and easy in Pella. But it is to be applied more generally, (1.) To the coming of Christ in the flesh to seek and save those that were lost; then the Sun of righteousness arose upon this dark world. Christ is the light of the world, the true light, the great light that makes day and rules the day (John viii. 12), as the sun. He is the light of men (John i. 4), is to men's souls as the sun is to the visible world, which without the sun would be a dungeon; so would mankind be darkness itself without the light of the glory of God shining in the face of Christ. Christ is the Sun that has light in himself, and is the fountain of light (Ps. xix. 4-6); he is the Sun of righteousness, for he is himself a righteous Saviour. Righteousness is both the light and the heat of this Sun; the word of his righteousness is so; it guides, instructs, and quickens; so is the everlasting righteousness he has brought in. He is made of God to us righteousness; he is the Lord our righteousness, and therefore is fitly called the Sun of righteousness. Through him we are justified and sanctified, and so are brought to see light. This Sun of righteousness, in the fulness of time, arose upon the world, and with him light came into the world (John iii. 19), a great light, Matt. iv. 16. In him the day-spring from on high visited us, to give light to those that sit in darkness, Luke i. 78, 79. Righteousness sometimes signifies mercy or benignity, and it was in Christ that the tender mercy of our God visited us. (2.) It is applicable to the graces and comforts of the Holy Spirit, brought into the souls of men. Grotius understands it of Christ's giving the Spirit to those that are his, to shine in their hearts, and to be a comforter to them, a sun and a shield. Those that are possessed and governed by a holy fear of God and a dread of his majesty shall have his love also shed abroad in their hearts by the Holy Ghost; and then the sun may be said to arise there, and to bring both a delightful day and a fruitful spring along with it. (3.) Christ's second coming will be a glorious and welcome sun-rising to all that fear his name; it will be that morning of the resurrection in which the upright shall have dominion, Ps. xlix. 14. That day which to the wicked will burn as an oven will to the righteous be bright as the morning; and it is what they wait for, more than those that wait for the morning.
