PJ just brought up an interesting point. Does us feeling "condemned" make an action a "sin?"
No. Sin is a specific action that has a particular effect on another.
We feel "condemned" for many things, for many reasons, some purely arbitrary.
You know from you mental health work, when emotions run wild, they are so
detached from reality, they cause chaos in someones life.
Paul though says this about righteousness and perfection.
I care very little if I am judged by you or by any human court; indeed, I do not even judge myself. 4 My conscience is clear, but that does not make me innocent. It is the Lord who judges me. 5 Therefore judge nothing before the appointed time; wait until the Lord comes.
1 Cor 4:3-5
Paul talks about ones conscience being an indicator of a problem, but not being
reliable, necessarily.
I speak the truth in Christ—I am not lying, my conscience confirms it through the Holy Spirit—
Rom 9:1
Therefore, it is necessary to submit to the authorities, not only because of possible punishment but also as a matter of conscience.
Rom 13:5
When you sin against them in this way and wound their weak conscience, you sin against Christ.
1 Cor 8:12
So Paul argues for sensitivity, and working things through. God is the ultimate judge,
but we should not judge ourselves for things that are not moral issues.
One reason for defined law, is to separate social obligations from actual sin before God.
It is why knowing the Lord and its precepts is a good thing to dwell on in your heart.
