An instructor at a U.S. artillery school saw many recruits over the decades, and he observed something. In the late 1950sand early '60s, the students were relaxed—so relaxed that artillery instructors wondered if they were getting through to them.
But in 1965, attitudes changed. Recruits studied intently. They took notes and asked questions.
The syllabus was no different. The faculty was the same. It's just that these recruits knew they were headed to the frontlines of a war.
This is Howard Butt, Jr., of Laity Lodge. Life has us in school daily, but are we paying attention? What life teaches us today will test us tomorrow. Our frontlines are never far . . . in the high calling of our daily work.
Put on the full armor of God so that you can take your stand against the devil's schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. (Eph. 6:11-12)
