keep on

"Keep on asking,

& you will be given what you ask for.

Keep on looking,

& you will find.

Keep on knocking,

& the door will be opened.

For everyone who asks,

receives.

Everyone who seeks,

finds.

And the door is opened to everyone who knocks."

Jesus speaking in Matthew 7:7-8 (NLT, 1st ed.)

Sometimes it's hard to "keep on"....
