What is the greatest danger to the church? Some people might think that the greatest danger to the church comes from external pressures like secularisation, or progressive ideologies or perhaps even the threat of radical Islam. However, Peter writes that the greatest danger to the church doesn’t come from external pressures, but rather, from within the church itself, from false teachers who veer away from Jesus and the gospel. These false teachers threaten the very foundation of the Gospel by undermining Jesus Christ. The only way to live faithfully for Jesus is to know him for who he truly is as he is revealed to us in the scriptures. If the church veers away from Jesus, the church will lose it’s only life source.
