First, how complete, or how secure is this salvation provided by Christ? Can we really be certain? What happens if we sin after turning to Christ in faith? Answering this query is the subject of 5:1–11.
The second issue addressed by Paul in 5:12–21 is “How could what one man did at one time in history have such an absolute effect on humankind?” Paul concisely answers this question by comparing the reign of death that Adam’s sin engendered with the reign of life made possible by Christ’s perfect sacrifice.
