<p>8:2 <i>If anyone thinks that he knows anything, he does not know anything as he ought to know- </i>This sounds like another of the allusions to Job (here to 26:14) in the New Testament- particularly once it is realized that 1 Corinthians has several other Job allusions. &quot;Thinks&quot; is literally to show, to account, to have reputation. We<i> all</i> have knowledge (:1)- not just some would be leader who says he has it. And anyway, it's not about knowledge- it's about whether God knows <i>us</i> in that we are in relationship with Him because we love Him (:3). This is the <i>knowledge</i> required., and it was this knowledge which was lacking in those who thought that their academic knowledge was what ought to make them be held in high repute. This is the force of the person thinking / showing / reputing that he 'had knowledge'. &quot;As he ought to know&quot; is an aorist really meaning 'as he ought to come to know'. It is the knowing of relationship which is in view, the process of knowing- and this is developed in the next verse. Their knowledge was just facts; Is. 28:13 speaks exactly to this problem by rebuking Israel for having no relationship with God but rather just treating His word as &quot;line upon line, here a little and there a little... precept concept upon concept&quot;. And this is how so much Bible study has been for many. They have glorified it in itself, and have apparently not come to spiritual relationship with God.</p>
