In John 14 we see Jesus, trying to encourage His disciples, telling them a wondrous truth. He said, "And I will pray the Father, and He will give you another (allos— another, but of the same kind and essence, of equal quality) Helper, that He may abide with you forever" (John 14:16).
Or, to put it another way, Jesus said, "I'm leaving. But I'm going to send Me to you in the form of Him— to be with you forever."
Really? But what does that mean? And what are the implications of that amazing truth?
