It is but human nature, fallen human nature, that man should love this present life better than the life to come.*
We are fallen, and human.
We are not terrible, or evil.
We try to be good parents, and good spouses and good friends, and we fail, often.
We don't fail because we are bad. We sin because we are frail.
Repressed with the human condition.
And I so often live here, right here amidst all I can see and touch and spend too much time thinking about that which is a mere echo of what is to come.
It's so easy to let distraction rule my days, with no thought to the eternal, the after, or the heaven I can bring to earth right now.
The Christian says, 'Creatures are not born with desires unless satisfaction for those desires exists. A baby feels hunger: well, there is such a thing as food. A duckling wants to swim: well, there is such a thing as water. Men feel sexual desire: well, there is such a thing as sex. If I find in myself a desire which no experience in this world can satisfy, the most probable explanation is that I was made for another world. If none of my earthly pleasures satisfy it, that does not prove that the universe is a fraud. Probably earthly pleasures were never meant to satisfy it, but only to arouse it, to suggest the real thing. If that is so, I must take care, on the one hand, never to despise, or to be unthankful for, these earthly blessings, and on the other, never to mistake them for the something else of which they are only a kind of copy, or echo, or mirage. I must keep alive in myself the desire for my true country, which I shall not find till after death; I must never let it get snowed under or turned aside; I must make it the main object of life to press on to that country and to help others to do the same.**
