Hebrews 4:12

For the word of God is quick, and powerful, and sharper than any twoedged sword, piercing even to the dividing asunder of soul and spirit, and of the joints and marrow, and is a discerner of the thoughts and intents of the heart.

Stories, analogies, anecdotes, or discussions of current events do not have the power or authority of the Word of God. Power in expository preaching comes from the Word, not from slighting it in favor of other themes.
