While thinking about Lent and Easter the humanity of Jesus comes to mind

It isn’t as though the Incarnation bringing together two natures is the very reason Christ agreed to become one like us is a mystery. But then, again if we delve into what Christ had before he decided to redeem us it is a mystery. Imagine, before he created everything that was for humanity there existed God eternally. We understand that God was not lonely nor did he need a human species to complete the creation of everything that exists. When did the thought, which is how he brought all that is into being, become his creation of man? In preparation for this newest of all he created he made angels. Since man needs the presence of angelic protection, and as we all can testify it is they who keep us from serious injury and even escape deadly circumstances away until it is our time to go home. No, it is more than a theological premise or a philosophic explanation that will uncover this mystery:

Creation is the foundation of “all God’s saving plans,” the “beginning of the history of salvation” that culminates in Christ. Conversely, the mystery of Christ casts conclusive light on the mystery of creation and reveals the end for which "in the beginning God created the heavens and the earth;” from the beginning, God envisaged the glory of the new creation in Christ. (CCC 280).

God himself created the visible world in all its richness, diversity, and order. Scripture presents the work of the Creator symbolically as a succession of six days of divine “work,” concluded by the rest of the seventh day. On the subject of creation, the sacred text teaches the truths revealed by God for our salvation, permitting us to “recognize the inner nature, the value, and the ordering of the whole of creation to the praise of God.” (CCC 337).

Of all visible creatures only man is “able to know and love his creator.” He is “the only creature on earth that God has willed for its own sake,” and he alone is called to share, by knowledge and love, in God’s own life. It was for this end that he was created, and this is the fundamental reason for his dignity: (CCC 356) What made you establish man in so great a dignity? Certainly the incalculable love by which you have looked on your creature in yourself! You are taken with love for her; for by love indeed you created her, by love you have given her a being capable of tasting your eternal Good. (St. Catherin of Siena).

Therefore, as we ponder the mind of God, which is beyond the ability of man, there is not a solution as to why God actually wanted a species like man except for the reason that the Love of God is so deep and so very generous that no other answer is possible; it is the very nature of God to continue with the unfolding of his kingdom that we were created to assist by our faith to live out this very ponderance of eternal life. God IS: and so we are the very essence of his being through grace which in itself is divine and eternal.
