They say that there are two seasons in Wisconsin: Winter and Road Construction. That’s not a bad analogy for what Paul’s describing here. To recap, two epochs, Adam and Christ (5:12-21), and since the latter has invaded the former, we straddle both, with schizoid experiences of ourselves (delighting in the good, doing evil) and of Torah (a delight—“the law of the Spirit of life in Christ Jesus” and coopted by sin—“the law of sin and death”). But this straddling isn’t the last word, and the Spirit will supervise the construction until all is renewed.
“If the Spirit of him who raised Jesus from the dead dwells in you, he who raised Christ from the dead will give life to your mortal bodies also through his Spirit that dwells in you.” So road construction is a weak analogy; caterpillar to butterfly might be better—and only the beginning.
