The Mysterious Incarnation (1 Timothy 3:16 (BC 18)

The incarnation of Christ is a very difficult doctrine for us to understand.  In fact, I would say that as human beings it is an impossible doctrine to fully understand. This doctrine teaches that Christ, who is from all eternity, took on real human flesh to ratify the promises of God. If this doctrine is so difficult to understand then why do we want to study this doctrine?  What could be beneficial about it regarding our day to day life?
