House of Prayer or Den of Thieves

Why did the LORD command the temple be built exactly as He specified? How is the LORD separating the wheat and the tares in this passage? Why was it that even though Christ taught daily in the temple that no man could lay a hand on Him? Why did Christ teach daily in the temple? Does the LORD speak to everyone? What is always the result of 'a Word in season'? Are good parents or a good heritage a prerequisite to salvation? Is Christ the Door to open and let some in or to shut and keep some out?
