Since every contemporary white Christian sermon is generally taught at a 2nd grade level (often as simple as "Jesus Loves You and So Do We") white Christian pastors figure that they should allow a note-taking style that is becoming to that of a 2nd grader. That's where fill-in-the-blank sermon notes come in handy.
When the mind starts to wander, pastors know that those blessed little blanks will bring 'em back. Expert level white Christians will have entered the church building prepared. Having previously received the scripture text in the church's weekly e-mail newsletter (and having subsequently read and/or memorized said text), this expert level white Christian will enter into their own little game of "predict the blank before the pastor says it aloud."
The golf pencil graphite will etch below the blank, and any correct predictions will result in a nudge in the ribs or a knowing glance to the white Christian family member sitting next to them. Conversely, malcontents in middle school might use the blanks as their own little personal game of "mad-libbs."
As if blanks weren't enough to keep the attention the blanks are digitally filled in on the screen so that white Christians can keep up.
Well-intentioned white Christians tell themselves that they will take the completed notes (or "answer key") home and place it inside their Bible or post it on their refrigerator. More than likely, however, these notes will be jettisoned during post-worship refreshments. There's only so much that a white Christian can hold onto. With a cup of coffee in one hand and a cookie/napkin combo in the other, the long-term storage of sermon notes for future contemplation is a necessary sacrifice.
