Webster's defines diligence as, "steady, earnest, and energetic effort : persevering application." Are we giving a "steady, earnest, and energetic effort" to serving the Lord? Do we steadily, earnestly, and energetically study His Word? Or, do we need to be more disciplined? Anyone who has trained for marathons or performed memorized solo work in music will tell you that it demands regular, disciplined effort. If our desire is to live in a way that pleases our Heavenly Father, this too demands diligence.
