Jonathan Edwards said this quote
“ In the soul where Christ savingly is, there He lives. He not only lives without it, so as violently to actuate it, but He lives in it, so that the soul also is alive. Grace in the soul is as much from Christ, as the light in a glass, held out in the sunbeams, is from the sun. But this represents the manner of the communication of grace to the soul only in part; because the glass remains as it was, the nature of it not being at all changed; it is as much without any lightsomeness in its nature as ever. 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. ”
