13It is right for them to be punished { God to punish them} because it is not those who merely know God's laws whom he considers to be righteous. On the contrary, it is only those who continually have obeyed all ◄of God's laws/of the laws that God gave to Moses► ◄whom God will consider righteous/whose record of sins God will erase►.
14Whenever the non-Jews, who do not have the laws God gave to Moses, naturally obey those laws, they prove that they have a law within their own minds, even though they do not have the laws God gave to Moses.
15They show that they know in their own minds what God commands in his laws MET, as each person in his very own conscience either accuses or excuses/defends himself concerning his own behavior.
16God will punish people at the time when he will judge them according to what they have thought and done. He will judge them even for the things that they have done secretly. He will judge people by authorizing Christ Jesus to judge them. This is what I tell people when I preach the gospel to them.
