The sin that Jesus bore, and that we are now empowered to live free from, includes all the sinful warrior deity images humans throughout history have projected onto God. In this way, the cross is at one and the same time the definitive revelation of the true loving God and the "crucifixion of the warrior god". And just as we should forever revolt against the sin and that was permanently put to death on the cross, so too followers of Jesus should forever revolt against the sinful warrior image of God that was permanently put to death on the cross.
[Those who accept] the Americanized, Constantinian paradigm [say:] We are of God; they are of the Devil. We are the light; they are the darkness. Our wars are therefore "holy" wars. With all due respect, this is blatant idolatry.
The holiness of the kingdom of God must be preserved. If Jesus refused to acknowledge and fight for Israel as God's favored nation- even though it was the one nation in history that actually held this status at one time- how much more must his followers refuse to acknowledge and fight for America as God's favored nation" To say it another way, if Jesus was committed solely to establishing a kingdom that had no intrinsic nationalistic or ethnic allegiances- not even with Israel- how much more should his followers be committed to expanding this unique, non-nationalistic kingdom?
Second, if you disbelieve in the reality of good and evil spirit agents, you fundamentally change the narrative of Scripture. The motif of spiritual warfare is a through-line of both the Old and New Testaments (NT). And in the NT, the meaning of what Jesus was doing in his life, ministry, death and resurrection is fundamentally tied up with the belief in spiritual warfare. Take away Satan, and you take away one of the most fundamental reasons Jesus came to earth!
