In Leviticus 16:14, when the high priest went into the Holy of Holies on the Jewish day of atonement, he took the blood of the bullock and sprinkled it with his finger on the mercy seat. Then he sprinkled the blood seven times before the mercy seat. According to Exodus 28:33-35, the high priest wore a robe trimmed around the hem with bells of pure gold. As long as those standing outside the Holy of Holies could hear the bells ringing, they knew that the high priest had not died in the presence of God and that God had accepted his sacrifice.
Compare that scenario to Hebrews 4:16, which is for us today: "Let us therefore come boldly unto the throne of grace, that we may obtain mercy and find grace to help in time of need." Unlike the high priest who went in once a year, we can come unto Him boldly twentyfour hours a day, every day, just as we are.
Are you backsliding? Come boldly. Have you fallen? Come boldly. Have you gone back into sin again? Name it, forsake it, turn your back on it, and come boldly to find grace and mercy to help in your time of need. Rush into the Holy of Holies in heaven (Revelation 11:19). There is a mercy seat sprinkled seven times with the Blood of Jesus Christ for you.
