In a broad sense God is omnipresent, which means that everywhere we go, He is there. But if we really want God with us, and more specifically, if we want Christ living in our hearts, then we must turn from our sin and believe in Him.
The beautiful baby in the manger came with an express purpose, and that was to die for the sins of the world. The birth of Jesus was so there would be the death of Jesus and, ultimately, the resurrection of Jesus. He was born to die so that we might live.
I personally know the pain of losing a child. And I think, for a parent, there is no greater pain than this. God knows all about that. He knows what it is like to lose a child. We talk about the sacrifice of Jesus, and justly so, as He came to this earth, laid aside His privileges of deity, and voluntarily went to a cross and died for the sins of the world. But let’s not forget the sacrifice of the Father who watched His Son enter this world.
Isaiah 9:6 sums it up perfectly: “For unto us a Child is born, unto us a Son is given; and the government will be upon His shoulder. And His name will be called Wonderful, Counselor, Mighty God, Everlasting Father, Prince of Peace.”
That gives us the perspective of both heaven and earth. From earth’s perspective, unto us a child was born. That is what we celebrate at Christmas. But from heaven’s perspective, unto us a Son is given. The Father sent the Son. He did this because He loves all of us, because He wants us to have the ultimate gift: the gift of eternal life. It’s the only gift that keeps on giving.
