Is Living Without Sinning Possible?

There is certainly one example in the merely human category: the Blessed Mother, although she had the singular blessing of being conceived without sin after the fall of Adam and Eve and also very blessed in being “full of grace,” as the angel Gabriel proclaimed to her at the Annunciation in Luke 1. And yet the Blessed Virgin Mary is the disciple par excellence in cooperating with God’s grace, as she exceeds in glory the angels who exceed her in nature. And that’s why she’s the queen of heaven and earth.

In addition, any human person who gains heaven will live completely without sin, as their wills be perfected in Christ, which means they will be impervious to sin (see Rev. 21:27).
