Mary was conceived just like every other human that has ever lived, with the sin nature passed to her through her father.
She too needed a savior, and when she was told that she would conceive and bear a son, He would not be born with that sin nature because God is His father, therefore the sin nature was not passed to Him, because Joseph was not his natural father, therefore the sin nature was not in Him.
“Mary was conceived just like every other human that has ever lived, with the sin nature passed to her through her father.............”
Mary was conceived naturallly, which is true. But the “Immaculate Conception” is not a physical thing. It is a spiritual favor granted to her by her Creator who selected her to be the Mother of his Son, Jesus.
Now, is it logical that God, the Almighty Father, would select a woman as a vessel for the Incarnation who was tainted with sin, and under the influence of Satan?
Since Jesus is the new Adam, then Mary is the new Eve. Selected by God, and conceived without the stain of sin, through no power of her or her parents, but by the grace of God.
Honoring Mary is merely recognizing her as the Mother of Jesus, the Savior. Also, we must NEVER FORGET that at the foot of the cross was the Mother of Jesus and a few other women named Mary, plus the Apostle John. Everyone else abandoned Jesus in his hour of darkness.
