The bet is God's title to His book
From Sensus Plenior
The bet ב is God's title to His book
As the first visible letter to the Tanakh, the bet is the title to God's book. It's metaphor is a resh with a horizontal line at it's base. The resh means 'a revelation' and the base is man. The Bet is 'A Revelation to man'.
God titled His book "A revelation to man". God is not discovered by man. No path, no discipline, no sacrifice, no work you perform will get you closer to God. His chosen title for His book tells us, that He makes himself known to us.
- Lu 10:22 All things are delivered to me of my Father: and no man knoweth who the Son is, but the Father; and who the Father is, but the Son, and [he] to whom the Son will reveal [him].
- Joh 1:18 No man hath seen God at any time; the only begotten Son, which is in the bosom of the Father, he hath declared [him].
