James 1:8

8A double-minded man, or, a man of a double mind. This sentence may be read by itself, as he speaks generally of hypocrites. It seems, however, to me to be rather the conclusion of the preceding doctrine; and thus there is an implied contrast between the simplicity or liberality of God, mentioned before, and the double-mindedness of man; for as God gives to us with a stretched out hand, so it behooves us in our turn to open the bosom of our heart. He then says that the unbelieving, who have tortuous recesses, are unstable; because they are never firm or fixed, but at one time they swell with the confidence of the flesh, at another they sink into the depth of despair.
