Tuesdays with Edwards!
But the soul of a saint receives light from the Sun of Righteousness, in such a manner, that its nature is changed, and it becomes properly a luminous thing: not only does the sun shine in the saints, but they also become little suns, partaking of the nature of the fountain of their light. In this respect, the manner of their derivation of light, is like that of the lamps in the tabernacle, rather than that of a reflecting glass; which though they were lit up by fire from heaven, yet thereby became, themselves burning shining things. The saints don’t only drink of the water of life, that flows from the original fountain; but this water becomes a fountain of water in them, springing up there, and flowing out of them; John 4:14 and ch. 7:38–39. Grace is compared to a seed implanted, that not only is in the ground, but has hold of it, has root there, and grows there, and is an abiding principle of life and nature there.
