A friend of mine describes the Christian life using a military metaphor that is both helpful and enlightening….I know – what a bargain!
Being a Christian is about learning the basics: Prayer; reading (i.e. exegeting and interpreting) scripture; Christ-likeness; learning the Fruits of the Spirit; living the sermon on the Mount; renewal of the mind; developing spiritual habits formed in the furnace of Trinitarian relationship, etc. These basics are like the “basic drill” an army unit performs to stay sharp. In other words, the existential reality for the army is the drill performed in peace-time: Marching; cleaning; inspection; fitness; and so on and so forth (one doesn’t want to push a military metaphor too far – there’s enough of that going on already)!
But the basics serve the special missions: Either planned or spontaneous mission/evangelism; specific seasons of ministry; short or long-term mission; local or national or international. In short, an Olympic athlete’s gold medal was forged on the running tracks of Trinidad; the swimming pools of Portugal and the cycling arenas of Argentina – the actual final in which it was won is almost a moot point! The basic drill serves the special mission.
