Tithing

They say that moth and rust corrupt
And 'though all you might try,
You cannot take your earthly gains
Along the day you die.

I won't say that I disagree
But just ‘tween you and me,
A way to overcome this plight
There may quite likely be.

You see, I take just ten percent
Of all that I do gain,
And put it in a special fund.
Now, why I will explain:

The plan is simply stated, for
With tithes and off'rings I,
Am making a down payment
On a mansion in the sky.
