"And they came with haste, and found Mary, and Joseph, and the babe lying in a manger" (Luke 2:16)
The mystery and miracle of the incarnation - God coming to take our humanity and our flesh, yet without sin. Luke quotes the message of the angel Gabriel to Mary:
"Thou hast found favor with God. And, behold, thou shalt conceive in thy womb, and bring forth a son, and shalt call his name Jesus. He shall be great, and shall be called the Son of the Highest. The Holy Spirit shall overshadow thee: therefore also that holy thing which shall be born of thee shall be called the Son of God. (Luke 1:30-32. 35).
The overshadowing of the Most High, the Father; the energy of the Holy Spirit; the enfleshment of the eternal Son - here were the Persons of the Godhead cooperating in a gracious act on behalf of lost men and women.
Lord Jesus, reign in us, we pray,
And make us as Thine alone,
Who with the Father ever art,
And Holy Spirit, one.
The Holy Spirit is indivisible from the Father and the Son, and He is all God and exercises all the rights of God and He merits all worship and all love and all obedience.
