Hereby is held forth an evident demonstration (and the greatest one that could have been given unto men) of the everlasting continuance of God’s mercies unto men, by this, that God is for everlasting become a man; and so we thereby assured that he will be merciful unto men, and that for ever. For as his union with our nature is for everlasting, so thereby is sealed up to us the continuation of his mercies, to be for everlasting; so that he can and will no more cease to be merciful unto men, than himself can now cease to be a man; which can never be. And this was the end [goal] of that assumption [of our nature to himself].
