you're right to press beyond generic theism, because not all monotheisms are created equal. the argument i've been making isn't just for belief in a god, but for the triune God revealed in scripture, and specifically for the coherence of the Christian worldview.
islam, for example, affirms monotheism and moral law, but it ultimately reduces God to pure will and transcendence, which creates philosophical problems. if allah is utterly unknowable and unbound by nature, even logic, then human reason and moral order become arbitrary. you get commands, not coherence. you get submission but not reconciliation.
Christianity by contrast offers a God who is both transcendent and immanent. a God who is personal, relational, and reveals Himself not just through law, but a historically attested incarnation. the moral law isn't just imposed, it's fulfilled. justice and mercy aren't in tension, they're united at the cross.
and yes, that hinges on whether Jesus of Nazareth is the promised messiah, but it's not a blind leap, it's a claim rooted in history, prophecy and resurrection. the coherence of Christianity isn't just philosophical, it's historical. the resurrection is the linchpin. if Christ rose, then Christianity isn't just coherent, it's true.
so i'm not arguing that belief in any god secures meaning. i'm arguing that Christianity uniquely does, because it grounds logic, morality and existential hope in a God who speaks, acts and redeems.
