Words They Live By

It isn't what they do,
It isn't what they say,
But when such people
Go on their way,
To other jobs, home,
Or whatever it is
They may be doing,
They leave behind them
A feeling, an atmosphere,
Not easy to put into words,
But we're happier, uplifted,
Decidedly better off.
I used to wonder,
What is it that could
Cause such a thing?
Then one day, very clear,
I saw what it is:
Why, they have Jesus
     In their heart --
           What He said,
                        And lived.
