The Role of a Grandparent 

The righteous flourish like the palm tree
and grow like a cedar in Lebanon.
They are planted in the house of the LORD;
they flourish in the courts of our God.
They still bear fruit in old age;
they are ever full of sap and green,
to declare that the LORD is upright;
he is my rock, and there is no unrighteousness in him.
Psalms 92:12-15 (ESV)
