Is relying on God for guidance comforting?

On another social network site I am on a member's son went missing and eventually found. He had ended his own life.
There was an abundance of sympathy with many members invoking God in their condolences.
One in particular took my eye.
"Thank you Lord God for giving R** closure so the healing process can begin"
Is this comforting to the griever?
Please be respectful in your replies.
