I have reason to think you are not what you say you are, though I must admit I can hardly understand much of what you said. So, @Xiang-Ivan, please tell us why you are here. This is not a site where believers can gain much. Are you questioning your beliefs? If so, then you are in the right place.

I see that the first group you, a believer, joined was the Sexual Deviant group. That's an interesting start.

On your profile, look for the heading, "Level." Next to "Level," click on your underlined points.

This will take your to the Levels Page that explains how to accrue points and perks with different levels.

Though I'm pretty sure you're a troll/fake profile, I'll tell you. You have to post and answer posts. The more you do that, the higher you go.

You can also find out in the FAQ's.
Q: How are the levels determined?

A: Please refer to the Level page for details on how levels are determined. The points/level system is just a way to help us reward active members by giving more access and perks to members as they increase their level.
