I'm very sorry for your loss. GP Jack loved living out there in the country and spending time gardening. I'm sure there is a beautiful garden in heaven. Praying for your family during this hard time. He will be missed.
I am sorry to hear of your loss. May you find comfort in the promises at Revelation 21:4 that reads: "And he will wipe out every tear from their eyes and death will be no more. Neither will mourning nor outcry nor pain be anymore. The former things has passed away." The Bible gives us hope that one day our dead loved ones will be brought back to life.
Please accept my sincere condolences to the family. May the God of all comfort give you the comfort you need to endure this difficult time and the days ahead (2 Corinthians 1:3,4)
