You could be living with a clear conscience! “Hebrews” explains two reasons you can live without guilt and shame.
One reason is because Jesus is better than not only all the priests, but even a High Priest.
Jesus’ life has no beginning nor ending. The Holy of Holies in the Tabernacle represented the very throne room of the Father. Only the High Priest could enter that room and he could go in only once a year. There was a rotation schedule for those serving as High Priest and replacements made for those who had died. The author of Hebrews told about Melchisedec (Hebrews 7:1-17). Moses considered him a priest. Melchisedec apparently had no birth or death. This passage is rather hard to understand, but the point is that Jesus’ life was eternal like Melchisedec’s. Therefore, His service as our High Priest never ends. He suffered for our sins (once for all) and entered into the presence of the Father forever as our representative.
“And every priest standeth daily ministering and offering often times the same sacrifices, which can never take away sins: But this man, after He had offered one sacrifice for sins forever, sat down on the right hand of God: from henceforth expecting till His enemies be made His footstool” (Hebrews 10:11-13 KJV).
“For Christ is not entered into the holy places made with hands, which are the figures of the true; but into heaven itself, now to appear in the presence of God for us: Nor yet that He should offer Himself often, as the high priest entereth into the holy place every year with blood of others; For then must He often have suffered since the foundation of the world; but now once in the end of the world hath He appeared to put away sin by the sacrifice of Himself” (Hebrews 9:24-27 KJV).
Therefore, we can live with a clear conscience because our sins have been paid for once for all and Jesus lives forever to keep on making intercession for us with the Father. Why should you live with guilt and shame when all your sins have been wiped out and your lawyer stands in the Court representing you every day?
A second reason you can live with a clear conscience is that Jesus completed a New Agreement that is far better than the Old Covenant with its rituals and sacrifices to atone for sins. His suffering on the cross settled your account with God and guaranteed your eternal life.
“For this cause He is the mediator of the new testament, that by means of death, for the redemption of the transgressions that were under the first testament, they which are called might receive the promise of eternal inheritance” (Hebrews 9:15 KJV).
“For by one offering He hath perfected for ever them that are sanctified” (Hebrews 10:14 KJV).
“And where remission of these is, there is no more offering for sin” (Hebrews 10:18 KJV).
So serve God with a clear conscience because all your sins (past, present, and future!!) have been forgiven. You don’t need a priest or rituals or sacrifices.
“How much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, purge your conscience from dead works to serve the living God?” (Hebrews 9:14 KJV; bold mine).
“Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water. Let us hold fast the profession of our faith without wavering; (for he is faithful that promised;)” (Hebrews 10:22-23 KJV;bold mine).
Living with a clear conscience means to be free from guilty feelings because of your sins. Of course, this kind of freedom requires self-examination and change as we become aware of new sins. But, it is a wonderful way of life, a rest and freedom from tyranny.
No one can appreciate the gospel unless they have a burden on their back…(i.e. Pilgrim in “Pilgrim’s Progress”). But no one has to remain burdened down with the weight of their wrong-doings. Listen to the good news that Christ Jesus has paid for your sins at the cross! That is why John Bunyan had Pilgrim’s burden fall off his back at the cross.
You, too, can be forgiven and live without guilt by acknowledging your sinful attitudes and acts and changing them. Then, with a clear conscience, continue serving God with joy and gladness because of His mercy and kindness.
