8:20-22 Bildad here assures Job, that as he was so he should fare; therefore they concluded, that as he fared so he was. God will not cast away an upright man; he may be cast down for a time, but he shall not be cast away for ever. Sin brings ruin on persons and families. Yet to argue, that Job was an ungodly, wicked man, was unjust and uncharitable. The mistake in these reasonings arose from Job's friends not distinguishing between the present state of trial and discipline, and the future state of final judgment. May we choose the portion, possess the confidence, bear the cross, and die the death of the righteous; and, in the mean time, be careful neither to wound others by rash judgments, nor to distress ourselves needlessly about the opinions of our fellow-creatures.

20. Bildad regards Job as a righteous man, who has fallen into sin.

God will not cast away a perfect man—(or godly man, such as Job was), if he will only repent. Those alone who persevere in sin God will not help (Hebrew, "take by the hand," Ps 73:23; Isa 41:13; 42:6) when fallen.
