Malachi 4:2,3

What a blessed account is here given of the Lord Jesus! under the figurative language of the sun, and the sun of righteousness, as the sole fountain of light, and life, and heat, and vivifying influence; Christ is described. And in how many ways, and by what a vast variety of means, the Lord Jesus becomes so to his people, it is impossible fully to describe. Jesus is all this, and infinitely more, from the first moment of conversion, through all the intermediate stages, until grace is consummated in glory. So that they all go forth under his blessed influence, and advance in the divine life with strength, and an assurance of firmness, as calves of the stall fattened and fed with constant attendance.
