I will never understand it, but by faith I believe it.
“The Word (Jesus) was with God, and the Word (Jesus) was God” and “the Word (Jesus) became flesh and dwelt among us” (John 1:1, 14, CSB).
“He (Jesus) is the image of the invisible God” (Colossians 1:15, CSB), “the radiance of God’s glory and the exact expression of his nature” (Hebrews 1:3, CSB). Before His incarnation, Jesus was always “existing in the form of God” (Philippians 2:6, CSB).
Jesus boldly and succinctly declared: “I and the Father are one” (John 10:30, CSB).
The doctrine of the Trinity is not logical. God is one God, but He has always been three! I can’t rationally or analytically figure that out, so I accept it by faith.
Once upon a time, sometime in eons past, Creator God didn’t decide that He would fashion time, space and matter and therefore need to be Father, Son and Spirit. He was always Triune! Jesus wasn’t created to interact with us, He always was as He always will be.
That’s why Christmas is so incredible. God became a baby! The Creator of heaven and earth was neatly wrapped into eight pounds of human flesh. “The King of the ages, immortal, invisible, the only God” (1 Timothy 1:17, ESV) was cradled in the arms of a woman He had created.
His throne became a feed trough. His royal robes were traded for swaddling cloth. The bouquet from the incense upon heaven’s golden altar was exchanged for the pungent odor of manure and hay. The anthem of attending angels, “Holy, holy, holy, is the Lord God Almighty, who was and is and is to come” (Revelation 4:8, ESV) was replaced by the bleating of sheep. God was born in a barn.
We know what Mary and Joseph couldn’t have fully comprehended. Jesus was born to die. The innocent baby would become the innocent sacrifice, given to atone.
That’s Christmas. “God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life” (John 3:16, NKJV).
