"Conscience". Not if you go on sinning. But if you repent and turn away from all your sins and idols, your "conscience" will be at rest. Beloved, if our heart condemn us not, then have we confidence toward God. (1 John 3:21) Christ took all our sins and guilt upon Himself -- all our iniquities were laid on Him.
Very well said. In the Book of Acts, we see an example of what repentance looks like. Fear fell upon the people and they forsook their evil deeds. Many of today's Christians would call that "works" because they have distorted what repentance really entails, which involves forsaking our sins.
Acts 19
[13] Then certain of the vagabond Jews, exorcists, took upon them to call over them which had evil spirits the name of the Lord Jesus, saying, We adjure you by Jesus whom Paul preacheth.
[14] And there were seven sons of one Sceva, a Jew, and chief of the priests, which did so.
[15] And the evil spirit answered and said, Jesus I know, and Paul I know; but who are ye?
[16] And the man in whom the evil spirit was leaped on them, and overcame them, and prevailed against them, so that they fled out of that house naked and wounded.
[17] And this was known to all the Jews and Greeks also dwelling at Ephesus; and fear fell on them all, and the name of the Lord Jesus was magnified.
[18] And many that believed came, and confessed, and shewed their deeds.
[19] Many of them also which used curious arts brought their books together, and burned them before all men: and they counted the price of them, and found it fifty thousand pieces of silver.
[20] So mightily grew the word of God and prevailed. (KJV)
