You will see your loved ones again, in a greater place, with the raiment of Light that only the Lord can provide, that I am sure of as I was blessed to have see these signs of things to come. Keep fighting for God's Kingdom is honoring their legacy and they are working with those in the Heavens for your success and God's Kingdom come. You are all here for a reason, try to remember where you came from and what you vowed.
