153 is a most interesting number. I am aware of the 153/sons of GOD connection that you may be alluding to.
So Simon Peter got into the boat and hauled the net to the land, full of great fish—one hundred fifty-three—and although there were so many, the net was not torn. John 21:11
However, the most compelling explanation I've seen so far for this number in John 21 is found in Ezekiel 47, (mainly because it is scriptural and fits the context of the time so well) which speaks of the apostles and workers of the gospel gathering all Israel through the work of the holy spirit.
Then said he unto me, These waters issue out [of the temple] toward the east country, and go down into the desert, and go into the [Dead] sea: which being brought forth into the sea, the waters shall be healed. And it shall come to pass, that every thing that liveth, which moveth, whithersoever the rivers shall come, shall live: and there shall be a very great multitude of fish, because these waters shall come thither: for they shall be healed; and every thing shall live whither the river cometh. And it shall come to pass, that the fishers shall stand upon it from Engedi even unto Eneglaim; they shall be a place to spread forth nets; their fish shall be according to their kinds, as the fish of the great sea, exceeding many. Ezekiel 47:8-10
The word
En in Engedi and Eneglaim means
spring, so the latter means the spring of Eglaim. Using gematria, in Hebrew the word Eglaim equals 153, and Gedi equals 17. I won't get into details, but 153 is a remarkable number intricately associated with the number 17 (9 x 17 = 153, for starts).
