How should Christians respond to false gospels?

The sermon emphasizes that Christians are called to oppose false gospels actively. This hatred must be a holy one, rooted in God's character, as these false teachings distort the truth of salvation, robbing God of His glory and leading many to eternal perdition. The preacher cites Psalm 139 to illustrate the need for a perfect hatred towards the systems and beliefs that contradict the gospel of grace. It's important for believers to love the people caught in these false doctrines while hate the lies that draw them away from the truth found in Christ alone, thus promoting a love that seeks eternal truth for all.
