God holds the key of all unknown (revised)

1
God holds the key of all unknown,
    And I am glad;
If other hands should hold the key,
Or if He trusted it to me,
    I might be sad.
2
If worries of tomorrow came
    To me today,
Without tomorrow's care as well,
Just what to do, I could not tell
    Or even pray.
3
The very dimness of my sight
    Makes me secure;
For, groping in my misty way,
I feel His hand; I hear Him say,
    My help is sure.
4
I cannot read His future plans;
    But this I know:
I have the smiling of His face,
And all the refuge of His grace
    While here below.
5
Enough; this covers all my wants;
    And so I rest;
For what I cannot, He can see,
And in His care I saved shall be,
    Forever blest.
Repeat the last line of each stanza.
