Let me begin by quoting Matthew 1:18, "This is how the birth of Jesus Christ came about: His mother Mary was pledged to be married to Joseph, but before they came together, she was found to be with child through the Holy Spirit."
Mary had never "known" a man before; she was a virgin in the very technical sense of the word (verse 23). Jesus was conceived by the Holy Spirit without the intervention of a human father. Joseph and Mary did not have sexual intercourse until after Mary gave birth to Jesus.
Now, for a brief biology lesson! When the male sperm and female ovum (egg) unite in what we refer to as conception, it is the male's seed that determines both the sex of the child and the blood type of the fetus. Therefore, when Mary conceived, it was in fact the very blood of God that began life in Mary's womb, and that later coursed through the veins of our Lord Jesus Christ.
It was blood that was uncontaminated by sin. The blood of God bypassed the genetic code of Mary and remained untouched by sin. Jesus was the spotless Lamb of God. That's why Paul could write in 2 Corinthians 5:21, "God made him who had no sin to be sin for us..." Hallelujah!
The blood that Jesus shed for our redemption was:
- the blood of God ONLY
- precious blood
- atoning blood
Perhaps I have taken the short, direct route to answer your question, but entire books have been written on this subject. This doctrine has been challenged, debated and ridiculed by those who try to eliminate our "crimson" salvation, but the Bible makes it clear in so many places that the blood of Jesus was truly an acceptable sacrifice for the sins of mankind.
In closing, let's allow Hebrews 9:12-14 to speak for itself:
"He [Jesus] did not enter by means of the blood of goats and calves; but He entered the Most Holy Place once and for all by His own blood having obtained eternal redemption. The blood of goats and bulls and the ashes of a heifer sprinkled on those who were ceremonially unclean sanctify them so that they are outwardly clean. How much more, then, will the blood of Christ, who through the eternal Spirit offered himself unblemished to God, cleanse our consciences from acts that lead to death, so that we may serve the living God."
Only the blood of Jesus--the pure, spotless blood of God qualified to save us from our sins!
