It is with great sorrow that I am sending my condolences on your recent loss. As one of Jehovah's Witnesses, I and would like to share a scripture that has benefited me and many people in time of grief. God reassures us of something wonderful in the Bible at Acts 24:15. It says, "There is going to be a resurrection." Along with God's promise to us at Revelation 21:3, 4 of sorrow, death, and pain being done away with permanently.
It is my hope that this bit of information is of comfort to you. Please be sure to find further information regarding the resurrection at: JW.ORG
May God be with you.
