Comparing Scripture with Scripture is lost on them. Bible study is about searching the Scriptures, comparing them, knowing who said what, when, and who they were speaking to or about, understanding that all the Bible is for our understanding, but it is not all for our doing today. We are to recognize the divisions and distinctions in GOd’s word that He Himself has placed there. But it is CRUCIAL to know where you are in God’s program as you study the Bible. Keeping the right Scriptures for the right time is essential. Just a small example would be to compare Matt. 6:14,15 with Eph. 4:32. Both are Scriptures from the NT. But they are DIFFERENT. WHICH is right for today?
And those that don’t are subject to the erroneous teachings of those who don’t. The blind leading the blind. So much confusion is avoided when the word is rightly divided.
