Visual effects. That’s what I liked best in high school chemistry class. The experiments that made a little puff of smoke, the ones that turned the smoke purple, or the ones that temporarily went awry and exploded into a little ball of fire. (The teacher always had a miniature fire extinguisher on his desk. He knew how adventurous our class members were.)
A demonstration concerning displacement involved a measuring cup, water, and a fist. Plunge your fist into a measuring cup full of water, and what happens? The water gushes out. Two things can’t occupy the same space at the same time. It was a simple demonstration, but the principle stayed with me.
Our hearts and minds can be filled with what isn’t good for them—fear, anxiety, selfishness, greed, and so forth—and get caught in the seemingly fixed ruts of wrong thinking and bad habits. But when we take in God’s word and commit ourselves to follow Scripture’s instructions and practice its wisdom, some of what is bad for us gets displaced with what is good, with what builds our spiritual health and well-being. “Displacement.” Faith in the truth and faithfulness to God’s ways are indispensable to it.
