Verse 12. Therefore - God is almighty, therefore he can easily destroy all his enemies: he is also merciful, and therefore will pardon good mens failings. Renderest - And this as he is obliged to do by his holy nature, so is he able to do it, being omnipotent, and willing to do it to the godly (which was the only thing that might be doubted, because of their manifold miscarriages) because he is merciful and gracious.
