What does Peter say about private interpretation of Scripture?
Peter states that no Scripture is a private interpretation. This means no one should build doctrine on isolated verses selected here and there, since that allows any teaching to be constructed. Instead, all Scripture from Genesis through Revelation should be used together, ensuring it fits, and apparent contradictions fade away upon study.
Les explains that the best way to study is to compare Scripture with Scripture, because Peter says in his little epistle that no Scripture is a private interpretation. Les teaches this means you cannot build a doctrine on one verse of Scripture here and one verse there, since you can build anything when you do that. Instead, it is our prerogative to use all the Scripture from Genesis through Revelation and see to it that it all fits. Seemingly contradictions may arise, but when you study, they just sort of fade away; they are not contradictory at all.
