My high school chemistry teacher wanted us to learn for ourselves that sodium is an unstable element. He gave each pair of lab partners a very small sliver of sodium to put in a Petri dish of water. Wow! That little piece whipped around that dish like a nuclear powered fish!
My lab partner wondered what would happen if you used a larger piece. He sneaked up when the teacher wasn’t looking and lobbed off a big chunk. When he plopped it in the water, it took off like a Fourth of July rocket and shot straight through the chemistry lab ceiling!
I remember very little about high school chemistry; but I do remember that sodium is an unstable element.
Jesus used the same method to teach us how to live the Christian life. Rather then just telling us, he showed us.
