Ephesians 6:10-18

Soldiers going out on duty have to be prepared for whatever might happen. In a very similar way, disciples of Christ must be prepared. Even though we might not always see it, there is a war going on, and Christ's disciples can expect to be under constant attack, not just from unbelievers around them, but from spiritual forces of evil.

The good news? Jesus has equipped every one of his soldiers with exactly the right kit to be able to withstand every attack, and not just that, but to advance with the gospel!
