I believe it's strand not strain. But I love this song.

I think it's a song by Dottie Rambo called the Unseen hand
it goes something like this
VERSE 1
There is an unseen hand to me
That leads through ways I can not see
We're going through this world of woe
This hand still leads me as I go

CHORUS
I'm trusting to the unseen hand
That guides me through this weary land
And some sweet day I'll reach that strain
Still guided by the unseen hand

VERSE 2
I long to see my Savior's face
And sing the story I've been saved by grace
And there upon that golden strain
I'll praise Him for His guiding hand

CHORUS
I'm trusting to the unseen hand
That guides me through this weary land
And some sweet day I'll reach that strain
Still guided by the unseen hand

TAG
Still guided by the unseen hand

Hope this is what you are looking for

God Bless

Am looking for this hymn for the pastor who preached our revival. It is the song that was being sung when he became a christian at age 7, 48 years ago. The only thing he knows that the hymn included the phrase "In the Unseen Hand(s) of God"
