Heresy is defined as choosing to believe something that contradicts what God reveals in Scripture.
In the sermon, heresy is explained as a choice—a decision to believe contrary to God's truth. The preacher emphasizes that if one believes based on personal choice rather than the objective truth of Scripture, they are committing heresy. For instance, choosing between grace and works is a heretical stance because true faith does not operate on choice but acknowledges grace as the singular means of salvation (Romans 9:16). The preacher urges that heresies serve to manifest genuine believers, demonstrating the necessity of truth as understood through Scripture and the inherent dangers of personal choice in matters of faith.
