God gave Ezekiel a detailed description of the Temple with measurements, locations of arches and windows, and a myriad of other details. The instructions are so vast that it takes up the next several chapters of Ezekiel. We know that the Temple resides within us because of Jesus’s gift to us of the Holy Spirit. If God had spent so much time describing in great detail the Temple and all the chambers and rooms for the different people groups, how much more do you think we should include other Christians in the Temple of our being? Ezekiel describes many different rooms, much like when Jesus told us he was going to make a place for us in his Father’s house. The Matthew Henry Commentary mentions that all the different rooms could be like the different church denominations. That makes sense, but notice that they are all under the same roof. I believe God will give us a certain amount of grace concerning our misunderstanding of the scriptures, though I think we should be diligent in seeking the truth as best we can. God will clean us up and refine our understanding as we submit to Him. The one thing that is very clear is that we need Jesus; without him, there would be no Priest for our Temple, and we would be lost forever. Seek first the kingdom of God and His righteousness, and all these things will be added to you.
But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. Matthew 6:33
And the man said unto me, Son of man, behold with thine eyes, and hear with thine ears, and set thine heart upon all that I shall shew thee; for to the intent that I might shew them unto thee art thou brought hither: declare all that thou seest to the house of Israel. Ezekiel 40:4
