Q: Can you help me to understand the armor of the spirit as described in Ephesians six?

A: Each of the types of armor mentioned in Ephesians six are terms taken right out of the Old Testament. And the main point Paul is making is that the Scriptures are the key to victory in terms of spiritual warfare. This entails learning the Scriptures well, studying them as a whole to have a comprehensive knowledge of “the whole counsel of God.” Second, it involves applying the Scriptures to our daily lives. A third principle is to deal with specific life issues by looking up passages (using a concordance or other study tool) that directly address these issues — studying, memorizing and using such verses to resist Satan. When Jesus was tempted three times, He resisted each by quoting Scripture directly relevant to each temptation. Obviously, He needed to know the Scriptures in order to do this. And this is exactly what Paul means when he urges his readers to put on the armor of God.
