Everyone hits a wall in Scripture. Anyone who says otherwise has not read much of it. The question is not whether you get stuck. The question is what you do when you are.
When you get stuck, reread slowly, ask who it was written to, check a clearer passage, write the question down, and keep going. Confusion is a bookmark, not a wall.
Here is a workable order of operations.
Read it again, slower. A surprising amount of confusion is just speed. Read the paragraph before it and the paragraph after it. Most difficulty dissolves once you see what question the author is actually answering.
Ask who this was written to. A command given to Israel at Sinai, a promise given to one king, and an instruction given to a church in Corinth are all Scripture, and all profitable, but they are not all addressed to your Tuesday in the same way. Figuring out the original audience is not lowering your view of the Bible. It is respecting it.
Check a clearer passage on the same subject. The plain parts of Scripture interpret the unclear ones. If a hard verse seems to teach something that contradicts a dozen clear ones, the problem is with our reading, not with the Bible.
Write the question down and keep going. This is the step people skip. An unanswered question is not a failure, it is a bookmark. Some of them get answered six months later by a passage you had not read yet.
And ask somebody. That is what a church is partly for. Nobody was meant to work this out alone in a room.
Hebrews 4:12 calls the Word living and active. Living things do not always cooperate on the first try. Stay with it.
