In a nutshell, this poem reminds me of GOD's encouragements that once we overcome we will truely know the rewards of our Eternal destination.
R E V E L A T I O N 2 : 7
"He who has an ear,
let him hear what the
Spirit says to the Churches.
To him who overcomes, I will give the right
to eat from the Tree of Life,
which is in the Paradise of GOD."
