Nahum 1:2-3a
A jealous and avenging God is the Lord; The Lord is avenging and [a]wrathful. The Lord takes vengeance on His adversaries, And He reserves wrath for His enemies. 3 The Lord is slow to anger and great in power, And the Lord will by no means leave the guilty unpunished.
Establish the need: Why do God judge the nations? We need to understand who God is and His attributes.
Purpose: We need to know God will judge sin because of His attributes, five we will see here in Nahum so that we will repent and trust in Christ to be saved.
