So do not worry or be anxious about tomorrow,
for tomorrow will have worries and anxieties of its own.
Sufficient for each day is its own trouble.
Matthew 6:34 AMP

I don’t know about tomorrow
I just live from day to day
I don’t borrow from the sunshine
For it’s skies may turn to gray
I don’t worry o’er the future
For I know what Jesus said
And today I’ll walk beside Him
For He knows what lies ahead

Many things about tomorrow
I don’t seem to understand
But I know Who holds tomorrow
And I know Who holds my hand

Ev’ry step is getting brighter
As the golden stairs I climb
Ev’ry burdens getting lighter
Ev’ry cloud is silver-lined
There the sun is always shining
There no tear will dim the eye
At the ending of the rainbow
Where the mountains touch the sky
