The inner sancturary is where God abides.
And our bodies are temples of the living God, symbolic of the tabernacle of the LORD.
All the members of the church are collectively the temple of God, the body of Christ.
And God's temple is holy; whoever destroys God's temple, He will destroy.
The law is written on the believer's heart, just as the tablets of the covenant were in the ark of the covenant in the inner sancturary.
So the ark represents our innermost being, the heart.
These bodies of ours are temporary; our tent will be taken down one day.
Even though our tabernacle is only for a short time, we look forward to a temple with its foundation on the rock, our new spiritual bodies.
