Shall We Know Each Other in Heaven?

Shall we know each other in heaven? It may astonish sonic of our readers to know that there is any confusion about this, but if they were asked to set forth from Scripture a solid explanation of the matter, they might be hard pressed to do it.
First, let us have it clearly before us that we are speaking of the time when all the saints will be at home in the Father's house, all in bodies of glory like unto Christ's. The subject of the knowledge of the souls and spirits of those who have already departed from this life to be with Christ is another matter. But the topic which we have chosen concerns not the unclothed state but the clothed state (spoken of in 2 Cor. 5), when we shall have our house which is from heaven—glorified saints in the glory with Christ.
There are not many express statements in Scripture on this subject, but there are enough that bear on it that we should not be in doubt.
