In the days before the death and resurrection of Jesus, no one could enter the most holy place in the temple. Only the high priest could go behind the veil into the presence of God. There were various rituals which the high priest needed to perform in order for him to be acceptable to God and to enable him to enter into the most holy place.
On the day that Jesus died, the veil in the temple in Jerusalem was torn in two from the top to bottom. (Matt 27:51) This was no coincidence. The veil was an extremely long and wide curtain and made from very thick material.
This is very significant for you and me, because the veil that has been separating the people from the presence of God has now been removed giving us access through Jesus into the most holy place of God's presence. Jesus came to die so that we can have a relationship with God, so that there is no separation anymore.
The veil signifies our sin and Jesus has endured death on a cross as punishment for our sin, he took our place and thereby removing the veil of sin forever. We do not need an invitation into God's presence, we did not earn it, but we received it as a free gift. "For by grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works, so that no one may boast." Ephesians 2:8-9
Do not let any lie keep you separated from the presence of God, Jesus has already paid the price, you now have access into the most holy place, with boldness and confidence, because you are a son and heir in His kingdom and have been set free by the blood of Jesus.
