My heart is not my own

My Heart is not my own,
Most of it is without me,
Given freely, taken lightly,
My own worthless credit
That costs me more than you know.

Do not take what you cannot spend,
Do not buy what you will not use,
Do not waste what has worth.
Do not give what is not yours to take.

Your heart is not your own,
It is worth more than you know,
You invested it in those you love,
And offered all that you had.

You gave it freely and not once
Asked for anything in return,
You will never know it's value
To those who are touched by it's grace.
