The conscience is an inner knowing or judgment between right and wrong. Even little children know when they have done something wrong. It is that inner sense that is quickened by the Holy Spirit when we are born again.
Webster’s Definition of conscience. 1a: the sense or consciousness of the moral goodness or blameworthiness of one's own conduct, intentions, or character together with a feeling of obligation to do right or be good
American Dictionary of the English language: Internal or self-knowledge, or judgment of right and wrong; or the faculty, power or principle within us, which decides on the lawfulness or unlawfulness of our own actions and affections, and instantly approves or condemns them. conscience is called by some writers the moral sense and considered as an original faculty of our nature.
Sin causes the “searing” of the conscience, as does corruption of the mind. In the old days an offender would be seared with a hot iron for everyone to see, as a mark of wickedness. When our conscience is seared, we justify our sin with carnal reasoning, while persisting in it with defiance against God, believing the lie of our right to do what we want. (1 Tim.4:2) Then the rule and reign of God over our lives is refuted. This is enmity with God and a dangerous place to be.
To be in right standing with God is a place of freedom in the Spirit. When we sin overtly, we try to cover it up (just like Adam and Eve in the garden, using fig leaves to hide their nakedness). Our fellowship with God is now broken, because of shame and guilt through defilement. The root cause is rebellion against God, which results in disobedience to His commandments.
The goodness of God leads to repentance and the good news is that when we do repent (turning away from our wicked ways), confessing our sin, the blood of Jesus cleanses us from all unrighteousness
“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)
Ask the Lord to also show you any area of your life where you have not forgiven yourself for your sin after you have confessed it to the Lord.
If there is any guilt or condemnation in your heart because of sin, you can be fully restored to freedom and liberty in the Spirit by bringing it before the Lord, asking Him to wash you and purify you by His precious blood washing
“If we confess our sins, he is faithful and just to forgive us [our] sins, and to cleanse us from all unrighteousness.”
Then you can come to Him without condemnation into the fulness of fellowship with Him.
“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.”
Hebrews 10:22 (KJV)
When our conscience is sprinkled by the blood of Christ, we are void of offense both towards God and man – restored to righteousness in right standing with God and men. What a glorious freedom through the provision of the blood of Jesus!
