For with thee [is] the fountain of life
Or "lives" F6: God himself is the fountain of living waters; this is a reason proving the happiness of those that trust in the Lord, and that they shall enjoy the above things; because with God the object of their trust is the fountain of life; not only of natural life, from whom they have it, and by whom it is supported, but of spiritual life, being quickened by him when dead in sin, by virtue of which they live by faith on Christ, and also of eternal life; and the phrase denotes, that life is originally in God as in its fountain, and that both the fulness of it is with him, and the freeness of it in the communication of it to others, as well as its continuance and duration;
in thy light shall we see light;
God is light itself, the Father of lights, and the former of it in every sense; in the light of his countenance, and the discoveries of his love, they that trust in him see light, or enjoy comfort; and in the light of his Son Jesus Christ, the sun of righteousness and light of the world, they see the face of God, and enjoy his favour, and behold the glory and excellency of Christ himself; and in the light of the divine Spirit, who is a spirit of wisdom and revelation, they see their sins exceeding sinful, their righteousness as nothing, and a preciousness in the blood, righteousness, and sacrifice of Christ; and in the light of the divine word they see the truths of the Gospel in their native simplicity and excellency, and the duties of religion to be performed by them; and in the light of faith, which is the gift of God, they have at least a glimpse of the unseen glories of the other world; and when the beatific vision shall take place, they shall see no more darkly through a glass, but face to face, even God himself, as he is in Christ.
