My condolences..
My Dad passed this Oct. on the 22nd with me by his side. So I can say I know how it is to loose some one you care about in this world. But at least you can have the comfort of knowing he's gone home now to a better place. Sounds like he has many rewards to reap for the seeds he's planted here.
I have no doubts God will be there to comfort you and your family through this time.
