Heirs of the kingdom, friends of Jesus, and beloved are just a few ways G-d defines us in the Bible. Its not easy to get over a tragedy and healing may not even happen in this lifetime. A traumatic event can change a person's brain chemistry as much as person suffering dementia. Nothing can reverse the damage done to the brain. In Psalms 56:8, we are told G-d collects each of our tears and the Bible closes with the promise that a day is coming in which there will be no more tears.
That will be the day we live in the fullness of the reality in which G-d defines us.
