Contemplating the incarnation and our Blessed Lord entombed in the virginal womb of Mary, Mother of God, the tiny Sacred heart of our Divine Lord beats from 6 weeks and His sacred heart is fully developed at ten weeks. He is fully God yet a tiny baby in the fetal stage - let us contemplate the beating sacred heart of our Divine Lord in the comfort of Mary's womb. The humility of Jesus in the womb a wonder for the angels and the saints.
