Perseverance.

Was reading Psalm 71 and thoughts of my Daddy-Lo came into my mind.

Vs 17-18:
O God, You have taught me from my youth,
And to this day I declare Your wondrous works.

Now also when I am old and grayheaded,
O God, do not forsake me,
Until I declare Your strength to this generation,
Your power to everyone who is to come.
