What should Christians do when faced with deception and false gospels?

In an age filled with deception and the proliferation of false gospels, Christians are called to stay rooted in the truth of Scripture. As described in the sermon, there is a growing apostasy where many are led away by teachings that emphasize human will and works. To combat this, believers must be diligent in studying the Word, growing in their understanding of true doctrine, and being discerning about the teachings they encounter. The call to proclaim the gospel remains vital, as it is through the proclamation of Christ's finished work that God draws His elect to salvation, providing hope amid a world of lies and confusion.
