A good prayer message of condolence to use on a card is "With deepest sympathy, may you feel God's comforting presence during this time of sorrow." Biblical quotes, such as, "The Lord is close to the brokenhearted; he rescues those whose spirits are crushed,” from Psalm 34:18, are also appropriate.
Christian messages of condolence often reflect the hope that God may heal the pain of the bereaved and guide them through their grief. Verses with this theme include, "He heals the broken-hearted and binds up their wounds,” from Psalm 147:3, and, "Don't be afraid, for I am with you. Don't be discouraged, for I am your God. I will strengthen you and help you. I will hold you up with my victorious right hand,” from Isaiah 41:10.
