Hebrews 9 reveals that maturity is not simply knowing you are forgiven, but living with a conscience that has truly been cleansed. The old system required repeated sacrifices because it could never fully remove guilt. Jesus entered once and for all with His own blood, not to temporarily cover sin, but to completely cleanse the inner man. Mature faith stops living under hidden condemnation and begins living with confident access to God, trusting that the sacrifice of Christ was fully enough and eternally complete.
