The most sacred area of the newly constructed temple was the inner sanctuary. The holy of holies. Once completed, no one but the high priest would be permitted to enter in, and that, only once a year. It was constructed, just like the rest of the building, with physical materials. Had it not been for the presence of God, it would have merely been a room. But, with its divine habitation, it became the most sacred place on earth.
Solomon could not determine if God would choose to take up residence in the sacred place. All the king could do was to prepare a place for Him to dwell. It would be at God’s sovereign pleasure whether He chose to manifest His awesome presence in that place.
Today, we are the temple of God. He chooses to dwell within us. We cannot force Him to. We can only prepare a place. It is at His discretion whether He is pleased to inhabit us fully or not. What kind of dwelling place have you prepared for your God?
