God had the Israelites build the tabernacle and later the temple, to show that He has a special place called the Holy of Holies.
However, what the Israelites made was only a symbol of the true Holy of Holies, for the Bible says,
“the Holy Spirit indicating this, that the way into the Holiest of All was not yet made manifest while the first tabernacle was still standing” (Hebrews 9:8).
Only the high priest descended from Aaron could enter the Holy of Holies on the earth, but when that earthly system ended, we learned the way into the true of Holy of Holies, which is heaven.
Jesus entered the Holy of Holies, and now we can follow Him, but only if we remain as faithful Christians.
