After my dad died in 2002, following (I hope and pray) my mom to God's hands, I had a dream.
I was walking arm in arm with my five brothers and sisters on a very wide road through gently rolling countryside on a mild day in the summer. My older brother's daughters and grandchildren were behind him, one sister's sons were behind her, another sister's three children were behind her. Cousins were spread out to the right and left of us . . . but there was no one in front of us anymore.
"The souls of the just are in the hands of God, and no misfortune shall befall them . . . ." (from memory). Pray for them anyway. Praying for the souls of my dad and mom and all who have gone before me is one way of honoring them. The fourth commandment doesn't end with our parents' deaths.
