Proverbs 3:3,4

"Do not let kindness and truth leave you;

Bind them around your neck,

Write them on the tablet of your heart.

So you will find favor and good repute

In the sight of God and man."

The virtues of mercy and truth 

that come from God are to become

part of us-outwardly in our behavior

for all to see as an adornment

of spiritual beauty,

and inwardly as the subject of our meditation.

Such inward and outward mercy and truth

is evidence of New Covenant salvation.

John MacArthur
