As Paul closed his letter to the church in Ephesus, he admonished them to be “strong in the Lord” (v. 10). This was necessary because of the challenges and opposition they faced (v. 11-12). This was done by putting on “the full armor of God” (v. 11, 13), which would enable them to “stand firm” (v. 11, 13-14). We face challenges and opposition to our faith today just as they did then. The way we can deal with it is the same – “put on the full armor of God.” What does this mean? How do we do it? Let us consider the passage.
