God has revealed Himself in important ways in our families, going all the way back to Abraham, the focus of the first and second readings. God promised Abraham and Sarah would have a child, even when the odds were so unlikely, and so He demonstrated His power when Isaac was born.
Jesus Christ was born of Mary, and then raised by Mary and Joseph. Indeed, just as with the Holy Family, God reveals Himself in the life and love we share with our families, as we grow together in virtues, opening ourselves to God's grace, as we strive to exhibit God's holiness.
As we reach the end of 2023, we're reminded of how our lives are touched by God's grace day by day, especially with those with whom we are closest.
