We glory in tribulations also; as old soldiers do in their scars of honour: see Galatians 6:17 2 Corinthians 12:9-11. Believers do not only glory in their future happiness, but in their present sufferings and afflictions: yet not so much in affliction itself, as in the issue and fruitful effects thereof, of which he speaks in what follows. Knowing, finding by experience, that tribulation worketh patience; not as if affliction of itself and in its own nature did this, for in many it hath a contrary operation; but God, who is the author and giver of patience, Romans 5:15, doth make use of it for this purpose; it is a means sanctified of God for the exercising, obtaining, and increasing thereof.
