Therefore, brethren, since we have full freedom and confidence to enter into the (Holy of) Holies (by the power and virtue) in the blood of Jesus. Hebrews 10:19
When you die and go to Heaven, it shouldn't be the first time you have been there. If the blood of Jesus has the power to remove my sin from the mind of God, it has the power to purge my consciousness and remove the remembrance of sin from MY mind.
"If you make much of the blood, the blood will make much of you." - Billye Brim
