③ to perceive someth. above and beyond what is merely seen with the eye

We have G2300-perceived his glory but no one has ever G3708-seen God with his physical eyes.
Further, 1 John 4:
See also No one has ever seen God. Really?

Strong's Greek: 3708. ὁράω (horaó) — 684 Occurrences15(John bore witness about him, and cried out, “This was he of whom I said, ‘He who comes after me ranks before me, because he was before me.’”) 16For from his fullness we have all received, grace upon grace.e 17For the law was given through Moses; grace and truth came through Jesus Christ. 18No one has ever seen God; the only God,f who is at the Father’s side, he has made him known.

Further, 1 John 4:
We could G2300-perceived God's glory but no has ever G2300-seen God himself.12 No one has ever seen God; if we love one another, God abides in us and his love is perfected in us.
By his Spirit, we have G2300-perceived that the Father has sent his Son.13 By this we know that we abide in him and he in us, because he has given us of his Spirit. 14 And we have seen and testify that the Father has sent his Son to be the Savior of the world.
i.e., G3708-seen with the physical eyes20 If anyone says, “I love God,” and hates his brother, he is a liar; for he who does not love his brother whom he has seen
We have not G3708-seen God with our physical eyes, and we have not even G2300-perceived God himself either. We could G2300-perceived God's glory (a manifestation) and we have G2300-perceived that the Father has sent his Son (a manifestation).cannot love God whom he has not seen [G3708].
