“If then your whole body
Is full of light,
With no part
In darkness,
It will be
As full of light
As when a lamp
Gives you light
With its rays.”
εἰ οὖν τὸ σῶμά σου ὅλον φωτεινόν, μὴ ἔχον μέρος τι σκοτεινόν, ἔσται φωτεινὸν ὅλον ὡς ὅταν ὁ λύχνος τῇ ἀστραπῇ φωτίζῃ σε.
Luke uniquely indicated that Jesus said that if their whole body (εἰ οὖν τὸ σῶμά σου) was full of light (ὅλον φωτεινόν), with no part in total darkness (μὴ ἔχον μέρος τι σκοτεινόν), it will be full of light (ἔσται φωτεινὸν ὅλον). Thus, it will be like a lamp (ὡς ὅταν ὁ λύχνος) that shines or gives light with its rays (τῇ ἀστραπῇ φωτίζῃ σε). Many ancient societies believed that the eye was the source of the light for seeing. If there was no darkness in a person, they would be like a bright light. Notice, that throughout history, holy people were usually portrayed with a halo light around them, emphasizing light and goodness. This was an inner light that would shine with its bright light. Your body would be like a lampstand shining light on the whole world. Do you light up a room when you arrive?
