In the Broadway play My Fair Lady, Eliza is courted by a man named Freddy. Freddy writes her love letters every day. But Eliza's response to all of these written promises is to cry out in frustration: "Words! Words! I'm so sick of words! Don't talk of stars burning above! If you're in love, show me! Don't talk of love lasting through time. Make no undying vow. If you love me, show me now!"

In the same way, Christians need to show their love and gratitude to God with actions, not just words.
