Having already noted the theology in both Proverbs and Sirach which depicts the personified Lady Wisdom as embodied in human figures (i.e., the ideal wife and Simon the High Priest), I have observed the same trend within the Gospel of John. In fact, the connections between Jewish literature describing Lady Wisdom and Jesus within John are far greater in number than the connections in Proverbs and Sirach (and I might not have even found all of them).
The primary conclusion of this evidence suggests that if the Gospel of John repeatedly depicted Jesus Christ as the embodiment and incarnation of Lady Wisdom, which itself is a personification rather than a literal person alongside Yahweh, then this is a strong indicator that the Fourth Gospel is not thinking in terms of Jesus consciously existing prior to his birth. Furthermore, if Logos and Wisdom were understood as synonymous terms (as Wis 9:1-2 suggests), then the theology of Jesus as the incarnation of Lady Wisdom needs to be read in conjunction with the prologue (John 1:1-18).
