'Conscience' in the Bible

I am telling the truth in Christ, I am not lying, my conscience testifies with me [enlightened and prompted] by the Holy Spirit,

Therefore one must be subject [to civil authorities], not only to escape the punishment [that comes with wrongdoing], but also as a matter of principle [knowing what is right before God].

Do not, for the sake of food, tear down the work of God. All things indeed are [ceremonially] clean, but they are wrong for the person who eats and offends [another’s conscience in the process].

It is good [to do the right thing and] not eat meat or drink wine, or do anything that offends your brother and weakens him spiritually.

But he who is uncertain [about eating a particular thing] is condemned if he eats, because he is not acting from faith. Whatever is not from faith is sin [whatever is done with doubt is sinful].
