My deepest condolences for the loss of your dear loved one. While nothing will completely take away your grief by meditating on Gods promises found in the Bible you can find real hope and the strength to keep going. My family and I have found the scripture at Isaiah 25:8 to be especially comforting. Here it promises that God "will swallow up death forever and the Sovereign Lord Jehovah will wipe away the tears from all faces."
I am sorry for your loss. May your family look forward to a time in the near future when the righteous ones will posess what God has purposed for them to have ever since He first created us. (Psalms 37:10,11,29)
