Yes, I have also experienced being deceived many times, maybe I do the same to my neighbor without knowing it, because I admit that even my mind and heart deceive me, and I am not a perfect person to say that I’m clean, so I have to test myself if I’m true or fake, as the saying goes, what you do to your neighbor is what they do back to you.
That is why I always ask God for forgiveness for what I did before.
Stop deceiving someone because you also deceive God by doing it.
Try to be kind and humble to your fellow believer, try to be true to them.
