I believe this is a gift of God to the surviving family. My paternal grandfather died in October 2002 at the age of 93. Other than athritis, he was healthy until 24 hours before his passing. His kidneys stopped working suddenly and his blood pressure dropped to the point where he was virtually unconscious. Just before he died, my dad says he became alert and said "take me Lord Jesus, take me." I personally think that God ushered those words as a witness to my father. His body was dying, but his spirit was quite alive.
Yes, absolutely a gift from God. I believe that the Lord was showing his Glory once again through Reagan.
Being spiritual, it's difficult for me to explain, but I believe that acknowledging look from Reagan was the "proof" (for us humans of faith) that Reagan was healed. That he has been restored. Though gone from the physical body, his spirit is alive and well with the Lord.
It gives me such hope.
