What does the Bible say about God's mercy and wrath?

Scripture emphasizes the dual nature of God's character: His mercy towards the elect and His wrath towards those who reject Him. In Romans 11, Paul exhorts believers to 'Behold the goodness and the severity of God,' indicating that God's kindness is for His people, while His judgment falls upon those who do not believe. This theme is further explored in various passages, including Psalm 2, which calls upon believers to serve the Lord with fear. It's crucial to understand that God's holiness dictates both His mercy and His wrath, showcasing that He is just and righteous in all His ways.
