You need to read the bible in regular order, i.e. from Genesis to Revelation, as you read any book series or watch any tv series. You'd naturally interpret later contents with earlier contents, and not the other way around, like most Christians do by interpreting the OT from a NT perspective. Actually, in storytelling, there's a term for that - retcon, Retroactive Continuity, which means editing the past or adding new contents in the past to accommandate the present plot, it's a kind of revisionism that often ruins a coherent narrative, "picking and choosing what to believe in the Bible" is exactly like that.
