In the context of war and righteousness, there is a profound distinction between the wars of this world and the spiritual allegiance owed to God. Many killings have been committed in the name of God, with holy wars leaving marks of fear and bloodshed across regions like the Middle East, and even influencing conflicts in other parts of the world. These wars, often fueled by passionate conviction, mirror a belief in righteousness that places the perpetrators above crime or sin. Yet, even in so-called just wars, people must be stirred to anger and hatred to kill, transforming peaceful citizens into warriors through training and incitement, not unlike the frenzy of holy wars elsewhere. God's supremacy over the nations reveals a different path. Scripture shows that He, the supreme Creator and Ruler, has promised to fight for His people supernaturally, negating the need for them to shed blood, provided they obey Him. Instances like the parting of the Red Sea and the defense of Jerusalem demonstrate His power to intervene, as He instructed His people to stand still and witness His salvation. However, Israel's history reflects a pattern of weak faith and disobedience, often leading them to war despite His promises. Their doubt and dissatisfaction became motivators for conflict, even when God allowed it as a consequence of their choices. As citizens of a heavenly Kingdom, our loyalties and submission must go to God before all else. We are not of this world's systems and are called to refrain from fighting in its wars. Our position as ambassadors of that Kingdom means we do not have the legal authority to involve ourselves in the conflicts of human nations. The central command remains clear: we must not kill. If we obey God's commandments and exercise faith in His promises, He will fight our battles, ensuring we never need to resort to violence. Only at the establishment of His Kingdom on earth will we participate in battle under His divine authority.

The Day of Trumpets signifies war in which the armies opposing the return of Jesus Christ are destroyed. God is a God of war who fights for His people against their enemies. He taught David how to wage war effectively. Jesus Christ will make war upon His enemies at His return. Righteous war occurs only when God commands it. God engages in war to destroy those who have become so wicked that they cannot repent, preventing further spread of evil. He also goes to war when His people are attacked without cause. The resurrected saints will form an army that wages war in righteousness and holiness. This war leads to complete victory for God and His forces, after which peace can be established for a thousand years.

The concept of God as a divine warrior stands at the heart of understanding righteous war throughout Scripture, beginning with the book of Joshua, where warfare dominates nearly every major theme, including the crossing of the Jordan, which functioned as a military invasion. Progressive commentators find this warfare troubling and attempt to dismiss it as borrowed from pagan literature about warrior gods like Baal, Marduk, or Ares, claiming it contradicts a supposedly gentler New Testament God. This view is contradicted by Scripture's consistent portrayal of God as a warrior from Genesis to Revelation, exemplified in Exodus 15:3, "The Lord is a man of war," and Psalm 18:34, where God teaches hands to make war. The Red Sea crossing in Exodus 14 establishes a template for divine warfare: God places His people in situations only He can resolve, promises to fight for them, tells them not to fear, and then destroys their enemies while His people remain unharmed. This event, requiring only faith and forward movement from Israel, typifies Christ's victory over Satan and represents baptism, since believers likewise contribute nothing to that triumph. Witnessing this deliverance produced godly fear and belief in Israel, demonstrating the proper response to God's warrior nature. Joshua 5:13-15 depicts the Commander of the Lord's army appearing to Joshua fully armed, sword drawn, revealing that God Himself is Israel's supreme military authority. His answer of "No" to Joshua's question about allegiance reflects His nonpartisan justice as Commander—He opposes sin regardless of who commits it, whether Canaanites or unfaithful Israel. This connects to the title "Lord of hosts" (Yahweh Sabaoth), used 242 times in the Old Testament, which conveys both military command and broader sovereignty over judgment, blessing, salvation, and creation itself, as seen in Isaiah 24-25. The command to annihilate Amalek perpetually, reaffirmed in Deuteronomy 25 and fulfilled partially through Saul, illustrates divine justice against persistent, unrepentant wickedness. Romans 1 and 9 provide the theological foundation for such judgments: humanity possesses inherent knowledge of God yet suppresses truth willfully, leaving all without excuse. As sovereign Creator, God justly uses nations—Israel against Canaanites, Assyria against Israel, Babylon against Judah—as instruments of righteous wrath, while also having authority to show mercy or harden hearts according to His purposes. These earthly judgments are not necessarily final, since the resurrection in Revelation 20 offers even the destroyed a future opportunity for salvation. Revelation 19:11-16 culminates this theme, portraying Christ Himself as the divine warrior who judges and makes war in righteousness, personally treading the winepress of God's wrath before establishing peace and His millennial Kingdom. Ultimately, war becomes righteous not because God is arbitrary or cruel, but because He alone possesses the authority, holiness, and justice to execute judgment against sin, ensuring that His interventions bring both justice to the wicked and peace to the faithful.
