How do you define this wonderful barometer that we have ignored for so long? This again shame the critics of the wonderful creature of God called man. I will enumerate a few of the function for lack of space will deny me to put here all, but you can always go read, study your bible for there a lot and i trust the holy spirit will reveal more to you.
Let me begin by saying this; Conscience is not the same thing as the Holy spirit. For you can have a defective conscience, a conscience that is no longer acting like a moral barometer because you have deadened it by your constant negative tendencies. But the holy spirit can not be defective, but can be grieved.
CONSCIENCE NOT SAME AS THE HOLYSPIRIT: Romans 9:1 I say the truth in Christ, I lie not, my conscience also bearing me witness in the Holy Ghost. All believer has the gift of the holy spirit while he possesses a conscience.
BIRTH OF CONSCINECE: Genesis 2:7 And the LORD God formed man of the dust of the ground, and breathed into his nostrils the breath of life; and man became a living soul. The formation of man was also the formation of conscience. A barometer was thus deposited in man to function.
FIRST DISPLAY OF CONSCINECE: Genesis 3:8-10 And they heard the voice of the LORD God walking in the garden in the cool of the day: and Adam and his wife hid themselves from the presence of the LORD God amongst the trees of the garden. And the LORD God called unto Adam, and said unto him, Where art thou? And he said, I heard thy voice in the garden, and I was afraid, because I was naked; and I hid myself.
A GOOD INNER JUDGE: John 8:6-9 This, they said, tempting him, that they might have to accuse him. But Jesus stooped down, and with his finger wrote on the ground, as though he heard them not. So when they continued asking him, he lifted up himself, and said unto them, He that is without sin among you, let him first cast a stone at her. And again he stooped down and wrote on the ground. And they which heard it, being convicted by their own conscience, went out one by one, beginning at the eldest, even unto the last: and Jesus was left alone, and the woman standing in the midst.
INBUILT WITNESS: Romans 2:15 Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)
PAUL’S REFERENCE: Acts 24:16 And herein do I exercise myself, to have always a conscience void of offence toward God, and toward men.
CONSCIENCE TESTIFIES TO OUR WORKS:2 Corinthians 1:12 For our rejoicing is this, the testimony of our conscience, that in simplicity and godly sincerity, not with fleshly wisdom, but by the grace of God, we have had our conversation in the world, and more abundantly to you-ward.
WEAK CONSCIENCE:1 Corinthians 8:7 Howbeit there is not in every man that knowledge: for some with conscience of the idol unto this hour eat it as a thing offered unto an idol; and their conscience being weak is defiled.
DEFECTIVE CONSCIENCE: Titus 1:15 Unto the pure all things are pure: but unto them that are defiled and unbelieving is nothing pure; but even their mind and conscience is defiled.1 Timothy 1:19 Holding faith, and a good conscience; which some, having put away concerning faith, have made shipwreck:
The question now remains if we have a good conscience, that inbuilt moral guidance?
