We know very little about heaven, but one theologian described it as "an unknown region with a well-know inhabitant," and there is not a better way to think of it than that.

Richard Baxter expresses the thought in these lines:

My knowledge of that life is small,
The eye of faith is dim,
But it's enough that Christ knows all,
And I shall be with him.

To those who have learned to love and trust Jesus, the prospect of meeting him face to face and being with him forever is the hope that keeps us going, no matter what life may throw at us.
