It is very sad to lose someone we love very much, and I am sorry for your loss. The physical body of your father no longer carries him in it, but rather your father is in his spiritual form, very much alive and well, in the spiritual realm. While you can no longer enjoy his physical presence, you can rest assured that he is with those who love him and look after him. While we may not be able to be aware of those in spirit, they are aware of us. I believe that through the power of our loving God, who knows all things and who is capable of that which is beyond our understanding, our loved ones in spirit are only a thought away from us. At times, you may feel that your father is nearby or with you. I hope that you may be comforted by this feeling, as it is genuine. Know that there are many who care about you and your father, and that they wish you peace of mind.
