I’m so sorry for your loss. I can only imagine how you must feel. I have found comfort in scriptures like Job 14:14,15 which remind me that God cares so deeply for us that he yearns for the day when he will bring us back to life on earth (John 5:28, 29). I hope that these words bring you comfort as well.
You may contact me personally if you wish to know more about the hope that God gives us in his word that there will be a resurrection.
