Contrast Isaiah 59:18 & Romans 12:19.
Compare Isaiah 59:18 with Romans 12:19 on God's role in vengeance.

Isaiah 59:18 — The Righteous Judge

- “So He will repay according to their deeds: fury to His enemies, retribution to His foes; He will repay the coastlands their due.”

- God Himself takes direct action; no delegation is mentioned.

- Vengeance here is judicial, measured, and perfectly aligned with each person’s deeds.

- The context (vv. 15-17) shows God putting on righteousness and salvation like armor, underscoring His personal, holy involvement.

- Key truth: Divine vengeance is certain, comprehensive, and righteous.


Romans 12:19 — The Call to Trust the Judge

- “Do not avenge yourselves, beloved, but leave room for God’s wrath. For it is written: ‘Vengeance is Mine; I will repay, says the Lord.’”

- Believers are expressly forbidden to retaliate.

- “Leave room” means stepping aside so God’s righteous judgment can operate.

- Paul quotes Deuteronomy 32:35, rooting the command in God’s own promise.

- Key truth: The same God who vows vengeance also commands His people to refrain from it.
