Q. Will we know our loved ones when we get to heaven?
Yes, I am convinced that we will. The Bible depicts heaven as a place where individual personalities are still distinct and recognizable. Jesus said, for example, that “many will come from the east and the west and take their places at the feast with Abraham, Isaac, and Jacob in the kingdom of heaven.” A hymn that I like very much (“Ten Thousand Times Ten Thousand”) sums up this idea well in what I consider to be biblical language:
Then oh what glad reunions on Canaan’s happy shore,
What knitting severed friendships up, when partings be no more.
Then eyes will shine with gladness that brimmed with tears of late,
Orphans no more fatherless, nor widows desolate.
I agree with your explanation here, but I’m curious how you reconcile it with Jesus’ statement that “in the resurrection they neither marry nor are given in marriage”.
I don’t actually see an inconsistency between people retaining their personalities/individual identities in heaven and their not retaining the roles that they had while on earth, for example, husband and wife. Marriage is something that God instituted at creation to serve specific purposes on earth. However, the foundation of a happy and healthy marriage is friendship between the spouses, and I am confident that that friendship continues in heaven.
