(Yea a sword shall pierce through thy own soul also.) Luke 2:35
But one of the soldiers with a spear pierced his side, and forthwith came there out blood and water. John 19:34
Two piercings--one of the body, one of the soul. One symbolic, one very literal.
Why does the Bible tell us of the blood and water from the side of Jesus? There is a theory, often called the "swoon theory", that says Jesus did not really die on the cross, but merely fainted. Later when he came to, his disciples took him away alive. Therefore, no death, no resurrection, no miracles and no salvation. The Devil never stops in his attempt to discredit the Word of God.
Of course, we know that the Romans knew how to kill a person. They sure did a lot of it. But the action of the Roman soldier, a way of proving death with his spear, refutes the swoon theory entirely. The blood of one who is dead separates into two components. This is proof that Jesus died on the cross.
After Jesus rose from the dead, He showed Thomas the wound in His side. But what of Mary and the sword that pierced her soul?
Such a way to tell of her suffering. Mary's pain is often neglected. Some will say it was because of the terrible way that Jesus died. When Simeon in the temple prophesied of her suffering, I believe this was to begin with claims that Jesus was illegitimate, and was to torment her throughout her life.
I heard Michael Savage (not his real name) tell his listeners that he would not accept a virgin birth as real. Of course, he is a Jew and carries on the attack that has gone on since the birth of Jesus.
The foretelling of Simeon and Anna tells of glory and suffering. How often they go together.
