Is It Singing

Is it singing I hear in my heart?
And why singing by the way -
Am I happy?
And how can I be happy
When I am stressed;
But am I really stressed?
Is it stress when I have to
Do a little work to keep
Body, soul and mind together?
I should not at all complain -
God is with me.
He loves and guides me,
Whispering in my ear,
Be content; don't fret my son,
For I love you.
I will lead you on to the end
And then you will not quarrel
With the singing in your heart
You are happy now,
But you will be happier then.
