“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, and since we have a great priest over the house of God, let us draw near with a true heart in full assurance of faith, with our hearts sprinkled clean from an evil conscience and our bodies washed with pure water.”
I really love this passage because it reminds me of one of the most amazing consequences of salvation. Since the blood of Jesus has washed away our sin, we are able to come before God be with Him.
Earlier in Hebrews 10 it talks more about how Jesus paid the price for sin. Read it.
