The misunderstanding of Romans 8:1 and the subsequent misapplication has come from years of not reading the scripture in its full context.

The fact that it starts off by saying "therefore..." indicates that the proceeding versus give substance to why the verse was written. Thus, I would encourage the reading of the proceeding verses and chapters also.

But in the meantime, before you complain or gossip about a brother or sister in Christ, keep this in mind, "there is no condemnation for those in Christ Jesus who do not live according to the sinful nature but according to the spirit."

Therefore, consider this:

Are the acts you are gossiping about and condemning according to the sinful nature?

Where the ask someone else was judging you over according to the spirits or according to the sinful nature?

Are you taking someone to court, or being taken to court?( Matthew 5:25, 26) is it over the sinful nature?

The fact that you are in court is evidence that there is condemnation over which a judgment is expected. Even something as small as getting a parking or speeding ticket falls in this category.

Is the person you are at odds with a christian?

I didn't ask if they went to church. I asked if they were a Christian.

Do they claim to believe in Jesus christ?

Would they acknowledge Jesus to be their savior?

You cannot answer for them. But this would serve as a great opportunity to learn what it means to acknowledge Jesus as Lord, explaining that this means to have Jesus as one's master. It's a great opportunity to witness and redeem a brother to oneself. But, instead, we take one another to court. (1Corinthians 6:1-8.)

Therefore, and this is just a question, are we then acting in christ?

There is condemnation in Christ.

It comes against those who, though they claim to be in christ, they are living according to their sinful nature.
