God warns us because He is compassionate

And the LORD God of their fathers sent warnings to  them by His messengers, rising up early and sending them, because He had compassion on His people and on His dwelling place. But they mocked the messengers of God, despised His words, and scoffed at His prophets, until the wrath of the LORD arose against His people, till there was no remedy. 2 Chronicles 36:15-16

The role and duty of those who are sent by God to proclaim His truth includes comfort and peace.  But more importantly they are sent to warn God’s people with “doctrine, for reproof, for correction, [and] for instruction in righteousness.” (2 Timothy 3:16)

God sends these messengers because He compassionately desires that we repent rather than continue in sin that condemns us.  Strong doctrinal preaching that calls for repentance is evidence of God’s love.

This same preaching is often [usually?] rejected, even by God’s people.

As the scripture clearly promises, those who reject God’s gracious warnings, will in the end suffer God’s righteous wrath.

In the end, there is no remedy from God’s final wrath.

Let us, therefore, worship the Lord for His gracious warnings, heed His words that lead to genuine repentance, and escape His fury by His grace alone.
