For when Gentiles, who do not have the law, by nature do what the law requires, they are a law to themselves, even though they do not have the law. They show that the work of the law is written on their hearts, while their conscience also bears witness, and their conflicting thoughts accuse or even excuse them on that day when, according to my gospel, God judges the secrets of men by Christ Jesus. —Rom 2:14-16

The gist of what he is saying is that even if you don't believe in God, but especially if you do, we know the difference between right and wrong. Just like when I used to go do things that were normal for most American teenagers/young adults, but felt that nagging sensation that I was doing something wrong. Maybe you never understood why you have that sensation or those feelings. I'm here to tell you it's because you were not made for this sin-filled world, you were made for paradise... heaven.

The good news is that God has given us a way back to himself—he said it in those early chapters of Genesis and he says it in different ways to reach us throughout the entire Bible: that he will bring us Salvation. That Salvation is through Jesus Christ. That nagging feeling in the back of your head or deep in your heart that tells you that something is not right is meant to push you towards him!

Let me encourage you to do so with a passage for St. Paul to the Ephesians that tells us we don't have to live with that nagging feeling that we are strangers in a strange land any more. God, in the form of his son Jesus Christ, has come to give us citizenship. I hope you take him up on it.

So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. —Eph 19-21
