Charles Ellicott Commentary James 1:3

"Knowing that the proving of your faith worketh patience." — James 1:3 (ASV)

Knowing this, that the trying of your faith works patience.—And this verse confirms our view of the preceding one; the habit of patience is to be the blessed result of all the weary effort under God’s probation. James the Wise had learned it long and painfully, and he returns to his exhortation of it again, especially in James 5:7-11 (see these verses).
