Sorry to hear of the loss of your mother. Take comfort in knowing she is now resting in the arms of our Lord and Savior. Psalm 18:2 "The LORD is my rock, my fortress and my deliverer; my God is my rock, in whom I take refuge. He is my shield and the hornof my salvation, my stronghold."
I'm sorry for the loss of your loved one, but try to think of him as sleeping. John 5:28 says, "Them hour is coming when all those in the memorial tombs will hear his voice and come out." So for now he is resting.
