Overview
The sacred veil (curtain) hung in the tabernacle and later the temple, separating the Holy Place from the Most Holy Place where God's presence dwelt. Only the high priest could enter beyond the veil once yearly on the Day of Atonement. This barrier represented humanity's sinfulness and inability to approach a holy God without a mediator and atoning sacrifice.
Key Scriptures
"But into the second [compartment] only the high priest enters, once a year, not without taking blood, which he offers on behalf of himself and the sins committed in ignorance by the people" (Hebrews 9:7, ESV).
"Therefore, brothers, since we have confidence to enter the holy places by the blood of Jesus, by the new and living way that he opened for us through the curtain, that is, through his flesh" (Hebrews 10:19-20, ESV).
"And behold, the curtain of the temple was torn in two, from top to bottom" (Matthew 27:51, ESV)—signifying Christ's sacrifice removed the barrier between God and His people.
Application
Believers can now approach God directly through Christ's finished work, enjoying intimate communion with the Father without intermediaries.
