Why is it important to contend for the true gospel?

Jude emphasizes the necessity of contending for the faith once delivered to the saints, highlighting that false doctrines can corrupt the church. The integrity of the gospel message—asserting that salvation is solely by grace through faith—must be maintained against anything that suggests human merit or free will plays a role (Galatians 1:8-9). This vigilance ensures that believers clinging to the true gospel are equipped to resist false teachings that compromise the gospel's power and clarity, thereby ensuring that the glory of God is rightly attributed to His sovereign grace in salvation.
