Frank Theodore’s family: I'm so sorry for your loss. I went through a similar situation and I was very helped by the hope that I found in the Bible in John 5:28, which says, "Do not amazed at this, for the hour is coming in which all those in the memorial tombs will hear his voice and come out". I am sending you a link with more information on this hope.

I am so very sorry for your loss. Please find comfort in God's sure promise of a resurrection as set forth in the Bible. (Acts 24:15; John 5:28,29) Those who are raised to life will have the prospect of never again being subject to misery, sickness, or death. (Revelation 21:4) I hope that reflecting on these thoughts and your wonderful memories will give you some relief during this difficult time.
