In a digital age where cyberattacks are common, our spiritual lives also face constant threats from false teaching. Just as we need firewalls to protect our devices, God has given us doctrinal firewalls to safeguard our faith—through biblically qualified elders, sound doctrine, and expositional preaching. In 1 John 4, we’re reminded that the Spirit of God empowers truth, while the spirit of error seeks to deceive—and only by grounding ourselves in God’s Word can we stand firm.
