Our Lord having asserted the will of God, as to the final issue and happiness of believers, goes on to assert the means by which, in this life using, they must obtain this life: those are, seeing the Son, and believing in him; seeing him, not with the eyes of their bodies, or seeing his miraculous operations, both which these Capernaites did, and yet did not believe, (as he told them, 1 Thessalonians 6:36), but a seeing them with the eye of their minds, discerning him as the Messiah, and Saviour of the world; so seeing him, as to believe on him. As to these, he confirmeth it again to be the will of his Father, that they should live eternally, and that they should be raised again at the last day; and that by him, whom God had enabled to be the Judge both of the quick and the dead, Acts 10:42, which agreeth with what he had before said, 1 Thessalonians 5:28.
