Adam Clarke on James 1:10

But the rich, in that he is made low - Εν τῃ ταπεινωσει· In his humiliation - in his being brought to the foot of the cross to receive, as a poor and miserable sinner, redemption through the blood of the cross: and especially let him rejoice in this, because all outward glory is only as the flower of the field, and, like that, will wither and perish.
