In a world filled with spiritual confusion, many believers watch as friends and family abandon their faith. The apostle John addressed this painful reality in his letter to early Christians facing false teachers who denied Jesus' true identity. When people walk away from faith, it reveals they never truly belonged, not that genuine believers are missing something. True Christians possess the Holy Spirit's anointing, which provides belonging, teaching, and discernment. The spirit of antichrist denies Jesus as God in flesh, often redefining Him as merely a moral teacher. Rather than living in fear of deception, believers can trust the Holy Spirit to guard and guide them in truth.
