If you had to choose one word to define these verses, what would it be?

I have always loved these two verse.  If you had to choose one word to describe what these verses are saying what would that word be?

Matthew 7:7-8(NKJV)

“Ask, and it will be given to you; seek, and you will find; knock, and it will be opened to you. 

For everyone who asks receives, and he who seeks finds, and to him who knocks it will be opened. 

For me that word would be persistence.  Keep asking, keep seeking, and keep knocking.
