OUTLINE:

A Good Conscience
Only submission to the Word of God and the Holy Spirit can educate us rightly so that we have good information to judge from.

Eph 3:20 [Amplified]
Now to Him who is able to [carry out His purpose and] do superabundantly more than all that we dare ask or think [infinitely beyond our greatest prayers, hopes, or dreams], according to His power that is at work within us…

1Co 16:14
Let all that you do be done in love.

Ac 24:16
“In view of this, I also do my best to maintain always a blameless conscience both before God and before men.”

Heb 13:7
Remember those who led you, who spoke the word of God to you; and considering the result of their conduct, imitate their faith. <-- NOTE: it says "imitate", NOT try to possess someone else's faith (aka - have your OWN convictions)!

Pr 4:7 The beginning of wisdom is: Acquire wisdom;
And with all your acquiring, get understanding.
- AND -
Pr 9:10 The fear of the LORD is the beginning of wisdom,
And the knowledge of the Holy One is understanding.

Conscience
If you want to enjoy the blessings of possessing your OWN convictions borne of a good conscience, you MUST begin by acquiring the Word of Truth!

Mt 6:33
"But seek first His kingdom and His righteousness, and all these things will be added to you." <-- Do NOT be deceived (like so many others) into thinking that blessings come ANY other way! LEARN THE WORD FOR YOURSELF!

“gold refined by fire”
Most likely refers to righteousness and/or faith, ala "So faith comes from hearing, and hearing by the word of Christ" (Romans 10:17). In other words, take in the Word of God!!! That is Christ's good counsel.

Don’t Fight Over Consciences
One of the most effective ways of diffusing emotional banter over right/wrong arguments is to objectively consider each party’s underlying knowledge and compare it to Holy Scripture.

READ YOUR BIBLE!!!

Jn 8:31-32
So Jesus was saying to those Jews who had believed Him, “If you continue in My word, then you are truly disciples of Mine; and you will know the truth, and the truth will make you free.”

Conscience
“conscience” = con + science = with + knowledge; means to know oneself; a person’s good conscience is based on data; it is not the source of data; rather, it is especially equipped to judge right from wrong.

“it is not even able to do so”
The human flesh is totally depraved, incapable of performing any good deed in God’s eyes. Only divine intervention, by grace, is able to save/deliver man from his destitution.

“it is not even able to do so”
Furthermore, man is totally blind left to his own devices, his conscience judging good and bad from a poor data set. This is why carnal man argues so vehemently against truth (from his perspective, he is functioning in integrity).
