Luke 2:30

For mine eyes have seen thy salvation,.... The Messiah, who is often so called; see Genesis 49:18. He goes by the name of "salvation", because the salvation of God's elect is put into his hands, and he has undertook it; and because he is the author of it, he has fulfilled his engagements, and has accomplished what he promised to do; and because salvation is in him, it is to be had in him; and in him the true Israel of God are saved, with an everlasting salvation: and he is called "God's salvation" because he is a Saviour of his choosing, calling, and constituting; whom he promised under the Old Testament dispensation and in the fulness of time sent; and who now appeared in human nature, and whom good old Simeon now saw, with his bodily eyes; a sight which many kings and prophets had desired, but were not favoured with; and also with the eyes of his understanding, with the spiritual eye of faith, as his Saviour and Redeemer; for without this, the former would not have been sufficient to have given such peace and tranquillity of mind, in a departure out of this world: for many saw him in the days of his flesh, who never saw his glory, as the Son of God, and Saviour of sinners; but such a sight those have, who have their understandings enlightened, and Christ, as God's salvation, set before them: they see him in the glory of his person, the fulness of his grace, the suitableness and excellency of his righteousness, the efficacy of his blood, and the perfection of his sacrifice; and as an able, willing, complete, and only Saviour: and such a sight of him, puts them out of conceit with themselves, and their own works of righteousness, as saviours; makes the creature, and all it has and does, look mean and empty; fills the soul with love to Christ, and a high esteem of him, and with joy unspeakable, and full of glory; it transforms a soul, and makes it like to Christ; gives it inexpressible pleasure and satisfaction; and makes it desirous, as it did this good man, to depart and be with Christ, which is far better than to live in this (in some sense) state of absence from him.
