I remember parts.
I'll let nothing separate me from the love of God.
I'll let nothing keep me from trusting His word
If I turn away from Jesus, tell me where can I go.
Trials and tribulations, no other help I know
I'll let nothing separate me from the love of God.
Upon my bed of affliction, my body was racked with pain
Doctors said it won't be long, you'll never be known again
But Jesus came by, stood by my bed
suffered my pain in my stead
I'll let nothing separate me from the love of God.
This is just from memory, so check the lyrics on you tube.
