@DonDemu, please how can we chat privately. I have something important to discuss with you.

Thanks brother.

I dislike people that are too religious.

Jesus was religious, he was disliked for being holy.

Well, if you conclude it's an advert I completely agree with you. Why? Because the product of Allah is expensive. Jannah is pricey, though most desirable. Hence, the need to convince people to buy. The Prophet ﷺ says that,

“Indeed the commodity of Allah is expensive, indeed the commodity of Allah is jannah (paradise)” (Tirmidhi).

Therefore, it's mandatory upon every Muslim to enjoin that which is good and forbid that which is forbidden. Allah says;
(وَلْتَكُنْ مِنْكُمْ أُمَّةٌ يَدْعُونَ إِلَى الْخَيْرِ وَيَأْمُرُونَ بِالْمَعْرُوفِ وَيَنْهَوْنَ عَنِ الْمُنْكَرِ ۚ وَأُولَٰئِكَ هُمُ الْمُفْلِحُونَ) [Surat Aal-E-Imran 104]

"Let there arise out of you a band of people inviting to all that is good, enjoining what is right, and forbidding what is wrong: They are the ones to attain felicity."

In sum, it's completely permissible to advertise and enjoin people to do an act of goodness that pleases Allah. One who makes such advert will earn rewards as those who saw the advert, que-in and make efforts to carry good needs. May Allah grant us understanding .
