Analysis of An angel came with crystal light

An angel came to break my chains
With crystal light that filled my veins
And turned to dust my aches and pains
With message of love long and true
He knew the things I had to do
He said my sins were absolved and few
But to ascend I must start anew
And live from the heart not merely the mind
Then fortitude my soul would find
Keep greed for things material bare
To show your God that you still care
Then your energy will fill the air
Yet abound with joy in your sweetest prayer
Listen not just merely hear
For what miracles you draw near
If needed shed a grateful tear
And realise that I am always here
