The apostle Paul understood what was happening in his day and it is still happening. We are in the midst of a war in which our opponents are spiritual forces. This is not a war we win by killing our enemies but rather by retaining our own integrity and our faith in Jesus who died so that we would be able to live.
When Paul tells his friends in Ephesus to put on the whole armour of God,he starts with the belt of truth. Paul’s correspondents would have been familiar with the Roman legionary,whose belt was the foundation upon which all of the other parts of the armour were attached, and this is the metaphor he uses for spiritual armour.
First of all, it means having no falsehood in our speech or our actions. Ever since the Holy Spirit had come upon the disciples at Pentecost, they had emphasised the need for absolute truth in all of their dealings with people both within and outside the Fellowship. Such conduct is the basis upon which every other aspect of life has to be built.
Secondly, we need to keep in mind that Jesus declared himself to be The Way, The Truth and The Life. Jesus is the truth, the foundation upon which all of the other spiritual armour is built. We all understand that no superstructure is better or stronger than the foundation upon which it is built. We have the strongest foundation upon which to build, the God who became man,and the man that death could not hold.
One of the situations we face in a post-modern society is that the common view is that each has their own truth and there is no absolute truth. We Christians, on the other hand, claim that there are absolute values,including absolute and objective truth. That truth is Jesus. If He could be sufficient for the Christians who were burned as
torches in the time of Nero, or who were put into the circuses of the Roman empire to be eaten by wild animals, then we in the 21st Century West have more than sufficient for our situation.
