Classic Poem

I do not need thy food, but thou dost mine;
For this will but the body's wants repair,
And soon again for meat like this 'twill pine,
And so be fed by thee with daily care;
But that which I can give thou needs but eat,
And thou shalt find it in thyself to be;
Forever formed within a living meat,
On which to feed will make thy spirit free;
Thou shalt not hunger more, for freely given
The bread on which the spirit daily feeds;
This is the bread that cometh down from heaven,
Of which who eats no other food he needs;
But this doth grow within him day by day,
Increasing more the more he takes away.
