So is the virgin birth that important? Can a person believe in Jesus without acknowledging it? I believe the virgin birth is important four at least four reasons.
First, it made possible for Jesus to be truly human, yet without sin. I affirm that the Scripture teaches that we are all sinners by nature and by choice. What that means is that we have inherited Adam’s original guilt from the beginning. Its in our nature. Because of our nature, we make behavioral choices to commit acts of sin. Because Jesus was conceived by the Holy Spirit, Christ stands outside of Adam’s guilt. I affirm that though Jesus was fully human, he neither possessed Adam’s guilt nor committed sin in thought, word, or action. The virgin birth provides for a sinless Christ.
Second, the virgin birth affirms the eternal pre-existence of Christ. One of the earliest opponents to the virgin birth was called adoptionism. Simply stated, adoptionism proposed that Jesus was the natural born child of Joseph and Mary, and that upon his birth he was adopted by God to be his son. The only problem with that misguided theory is that is disallows the eternal pre-existence of Christ. I affirm that Jesus has always existed as the second member of the trinity, without beginning or end.
Third, the virgin birth allows for the incarnation. He would be called, “Immanuel, meaning, God with us.” Jesus came into the world fully God as though not man at all, and fully man as though not God at all. Perhaps the best way to illustrate this is to think of a man wearing a suit. Suppose the white dress shirt illustrates the divinity of Christ. Everyone can see the white shirt. But suppose the man then puts on his suit jacket, representing the humanity of Christ. Does the suit jacket render the white shirt null and void? No. Just because the man puts on the jacket doesn’t mean the white shirt has disappeared. You can still see some of it, though in a limited form. This is what Paul expressed in his Hymn to Christ in Philippians 2:5-11. Jesus emptied and condescended. Why? He came to be with us to identify with us in order to save us.
Finally, the virgin birth is important because it speaks of our spiritual need. Our salvation must come from the Lord. There was no human means possible for us to save ourselves. An intervention was necessary. On one hand we usually get warm fuzzies thinking about the Christmas story. We imagine the nativity with the baby in the manger surrounded by the adoration of those who gathered. But we need to remember that the reason Jesus came was because we were dead in our trespasses and sins, under the wrath of God. The Christmas story is at the same time humbling yet hopeful.
So yes, it matters!
