I Corinthians 15:45: “Thus it is written, ‘The first man Adam became a living being;’ the last Adam became a life-giving spirit.”
Richard Gaffin unpacks the meaning of “life-giving S/spirit” here:
“Resurrection is here nothing less than the counterpart of creation. The resurrection of Christ is the beginning of the new and final world-order, an order described as spiritual and heavenly. It is the dawn of the new creation. It is the start of the eschatological age.”
“As birth is characteristic of the old aeon, the sarkic world, so resurrection marks the beginning of the new aeon, the eschatological, pneumatic world.”
