Exit the letter

Please forgive me
Dear Lord I'm writing you this letter
I know it's been long
I still remember how you hold me in your arms
You told me in the dream that i was heading downstream
You know I'm hard headed
I went to church on Sundays
But never had my heart in it
Like a hippogriff on Monday
I was back on a corner straight flipping it
Call me young and ignorant it wasn't too long before a dream came true
