Who Can Ever Know the Heart?

Can my heart ever know
Can its fruit truely show
All the stuff that's in store,
Good or bad from the core?

Can more debts that I bear,
Mean more love that I share
To the one who forgave,
And then, gave all to save?

Chorus:
Who can ever know the heart---?
How does one ever get that smart?
Can I be sure that my heart won't ever be deceived?
Well, endless searching can't fulfill
But God and His free grace will.
I must trust my heart to God and believe.

Well, one son said, "No! No!"
Then he thought he'd best go.
He came through, though delayed.
It was good he obeyed.

The next son said, "Yes! Yes!"
Then forgot all the rest.
He was good to intend,
But was bad in the end.

(chorus)

Does a pat on the back,
A reward or the lack,
Slows me down and give pause:
Do I work for applause?

Is that smile real inside?
Do you feel but you hide?
Are impressions you leave
Something real or perceived?

Bridge:
Lay your heart upon Christ Jesus
Let Him work through what you do
You can hide in His perfect righteousness
Stake your life upon Christ Jesus
In His likeness we become
Our reward is with Jesus, aren't we blessed?

(chorus)
