Here's a poem called "Good Friday" by George Herbert, who has a fascinating story. This poem is good to ponder any time, but especially when the leaves are falling. It might be hard going but it gets more powerful as you make your way through it. 

Good Friday

O my chief good,
How shall I measure out thy blood?
how shall I count what thee befell,
And each grief tell?

Shall I thy woes
Number according to thy foes?
Or, since one star showed thy first breath,
Shall all thy death?

Or shall each leaf, 
Which in Autumn, score a grief?
Or cannot leaves, but fruit, be sign
Of the true vine?

Then let each hour
Of my whole life one grief devour; 
That thy distress through all may run,
And be my sun.

Or rather let
My several sins their sorrows get;
That as each beast his cure doth know,
Each sin may so.

Since blood is fittest, Lord, to write 
Thy sorrows in, and bloody fight; 
My heart hath store, write there, wherein
One box doth lie both ink and sin:

That when sin spies so many foes,
Thy whips, thy nails, the wounds, thy woes,
All come to lodge there, sin may say,
No room for me, and fly away.

Sin being gone, O fill the place 
And keep possession with thy grace 
Lest sin take courage and return,
And all the writings blot or burn.
