When 9/11 happened, many people were shaken; when we heard about schools being terrorized by unstable students with guns and mass shootings, we were shaken; when hurricanes and tornadoes touch down, destroying homes and killing people, we are shaken. When we hear about churches allowing women to pastor, homosexuals to be pastors, child abuse among the churches, people embracing false teaching, and people are leaving churches to pursue the world, we should be shaken! It is no wonder that John wrote this passage for his readers. They needed to understand two things; first the antichrist is coming and second be steadfast in the truth. As he lays out these things, he offers to them and to us how we can be steadfast, immovable in the truth.
