He shall pray unto God ... - That is, when he fully understands the design of affliction; and when his mind is brought to a proper state of penitence for his past conduct, then he will find God merciful and ready to show him kindness.
And he shall see his face with joy - The face of God. That is, he shall be able to look up to him with peace and comfort. This language is similar to that which is so frequently employed in the Scriptures, in which God is said to lift upon us the light of his countenance. The meaning here is, that the afflicted man would be again permitted to look by faith on God, being reconciled to him, and would see in his face no indication of displeasure.
For he will render unto man his righteousness - He will deal with him in justice and equity. When he sees evidence of penitence, he will treat him accordingly; and if in the afflicted man he discerns true piety, he will regard and treat him as his friend. The meaning is, that if there is in the sufferer any sincere love to God, he will not be indifferent to it, but will treat him as possessing it. This is still true, and universally true. If there is in the heart of one who is afflicted any real piety, God will not treat him as an impenitent sinner, but will manifest his mercy to him, and show to him the favors which he confers only on his friends.
