8:20 Behold - God who will not help the evildoer, will not cast away a good man, tho he may be cast down. Yet it may be, he will not be lifted up in this world: and therefore Bildad could not infer, that if Job was not restored to temporal prosperity, he was not a good man. Let us judge nothing before the time, but wait 'till the secrets of all hearts are revealed, and the present difficulties of providence solved, to universal and everlasting satisfaction.
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.
