Thinkin' this is the one you are you looking for:

You Alone Are My Sunshine

Chorus:
You alone are my sunshine
You alone make my day
You took my darkness
and you turn my night into day

Take me up your highway
take me all the way home
take me when you ride in the sky
there I will never be alone

Chorus

Jesus you're my savior
You're my master
You're my Lord
You bore my sin when you died on the cross
and raised on Easter morn

Chorus

When I hear that trumpet
I will know that He has come
When I hear that trump-a sounding
I will know my work is done

There are slight differences to this because it is bluegrass gospel

I need christian lyrics to the old song, you are my sunshine.
