Exodus 39:32 Thus was all the work of the tabernacle of the tent of the congregation finished: and the children did according to all that the Lord commanded Moses, so did they.
After a detailed description of the construction of the tabernacle and all its furniture and instruments, it was finally finished according to the Lord’s command. The tabernacle was built according to the pattern of the heavenly tabernacle. Every detail was to be repeated exactly according to God’s Command, for it was designed to be the earthly dwelling place of the heavenly, invisible, eternal God. No detail could be missing, for God lived there.
Israel did the work exactly according to the pattern commanded. This work was no trivial matter, for it was a big thing to know where God lived and how to approach Him. It was important to do according. The God who was so far away, infinitely far, because of man’s sin, has determined in His love to live with His people, and so He created a way to approach Him in a place He could be present on earth. The Invisible will inhabit the Visible; the spiritual touches the physical; the eternal enters the temporal; the heavenly comes into the earthly; the holy cleanses the sinful.
All of this happened when God became a Man and dwelled (tabernacled) among us. Jesus Christ was foreshadowed in the tabernacle. He replaces the tabernacle. He is the meeting place between God and humans. Then the body of Christ, the invisible church of all believers, the gathering of Christians becomes the Tabernacle of God.
The faithful obedience, the doing what God commanded, for NT believers is repentance and faith in the Gospel. The invisible gospel becomes visible to us in the water and bread and wine of the Sacraments. The Spirit makes a holy place in our heart for the indwelling of a holy God. We respond to Grace and construct a tabernacle in the heart by believing in Christ.
