The turn of a screw

Life goes round and round
Just like the turn of a screw
We can't see too far ahead
But we can look back a bit!
Too many turns sometimes
Too many little twists to see
But always as we look back
We can see the turning of that track
We can see the way things were!
I aim to reach that top
Where the screw driver fits
I aim to be one who climbs up hill
For if I stop half way up
I'll never get to the top
And that's where I wish to be
Way up there with the Lord
Way up there where I can see
Every little twist and turn
Written in my Saviour's book
Written where no-one else can see!
