For with what judgment you judge, you shall be judged: and with what measure you measure, it shall be measured to you again.
All Commentaries on Matthew 7:2 Go To Matthew 7
Hilary of Poitiers
Otherwise; He forbids us to judge God touching His promises; for as judgements among men are founded on things uncertain, so this judgment against God is drawn from somewhat that is doubtful. And He therefore would have us put away the custom from us altogether; for it is not here as in other cases where it is sin to have given a false judgment; but here we have begun to sin if we have pronounced any judgment at all.
