God rescued Israel from the Egyptians, but He also made a way to rescue them from their own wickedness and rebellion. He allowed them to make sacrifices and draw near to His temple through ceremonial cleansing. God allowed these things to be mediated through people with a specific role, called priests. However, these priests also had their own sin and faced their own mortality as well. Jesus has now come as our better high priest, making full sacrifice once and for all and mediating eternally on our behalf so we can draw near to God.
