Romans 1:32b

Although they know God's righteous decree that those who do such things deserve death, they not only continue to do these very things but also approve of those who practice them.

(v32, NIV)

This verse goes on to say a bit more about these people. We learn that they have knowledge of God's standards. Paul already wrote about something similar back in verse 19. However, this time it's more than just knowing God because God has made it evident to them. This time, God and his standards are known. They know God and his standards. By knowing God's standards, they also know that breaking these standards deserve death.

So, they know about God and his decrees. They also know that going against these decrees deserve death. What does this mean? If we look back at verse 20 we have already seen that these people are without excuse. They know God and his laws so they can't claim to be ignorant of the very things they disobeyed.

You know God and his decrees. You know whether you care to admit it or not. You know whether you're even aware of it or not. Since you know, there is no excuse. You can't claim to have not known because God has made it known to you.
