Both readings today tell stories of women conceiving a child at an old age when such a conception was impossible. Those stories are in the Bible to remind us that all births are miraculous in that the souls are direct gifts from God.
God spoke to Jeremiah, saying, “Before I formed you in the womb I knew you.” God could say the same for reach of us.
When I was young I always heard that our souls were in heaven before we were born., and I used to say, “Yes, I remember some of that, but not much.”
In the first thousand years of Christianity the saints leaned on the teachings of Plato who thought that our souls came down from heaven to be imprisoned in bodies for a time. They saw themselves as symbolized by sunflowers that keep turning towards the sun with the hope of getting back to their real home.
In the second thousand years of Christianity we have seen more sense in Aristotle’s teaching that God creates our souls at our moments of conception.
Whatever your philosophical bent you can thank God for having made you wondrously well.
