The gates are unique to each person. When you go through the final gate, it's like the Old Testament priest going into the Holy of Holies. Everything else was external. It was just he and God. We all have different gates.
Some people have gates called children.
Others have a gate called a profession. Others have possessions, or addictions, or a finely cultivated image. Anything that's external, that's telling you something about yourself, God has to take it to the altar and kill it, so He can be your all in all. We have to be grateful to God because He drives us to Himself. But He does it with love.
