Elders

I owe almost everything I am and everything
I have to the elders who invested in me.
Thank you, God, for those who came before. 
Now I'm 34 and I see many
of those gracious, elderly saints growing
frail and passing away. I mourn. They were
the ones who had walked ahead,
the ones who knew, the ones I could look to. 
Where do I look now? And how do I thank them
for giving me my eyes?
