How do Bible Unitarians interpret “the last Adam became a life-giving Spirit” (1 Corinthians 15:45) without affirming Christ’s divinity?

In 1 Corinthians 15:45, Paul writes: >“The first man Adam became a living being; the last Adam became a life-giving spirit.” (ESV) In context, Paul is contrasting Adam and Christ, particularly in relation to life and resurrection. The phrase “life-giving Spirit” seems to attribute to Jesus a role that, elsewhere in Scripture, is closely associated with God (i.e., giving life; cf. Genesis 2:7, John 5:21). From a Bible Unitarian perspective, Jesus is understood as a fully human Messiah and not ontologically divine. - How is the ability to give life explained without attributing divinity to Christ? - How is this reconciled with other passages where giving life appears to be a uniquely divine prerogative?
