The Place of Sin in Biblical Theology

In reading Neal Plantinga's Engaging God's World I came across this striking quote:

“The Bible’s big double message is creation and redemption. Sin intervenes but never as an independent theme. Thus St. Paul, the Bible’s chief theologian of sin and grace, speaks of sin in terms of what it is against.” ~ Engaging Gods World, 87

What are your thoughts? Has Plantinga correctly framed sin within redemptive history, biblical theology?
