When I was 12 I had no idea how this devil's deception work. But now I think I got it. So imagine a thief broke into your house in the middle of the night. And your neighbours saw him and they called you to inform about it. But you come out of your bedroom to see if he is there but you don't find him anywhere, so you don't call the police. Thinking the neighbours are playing April Fool in the month of May. Now the theif is well at hiding and one by one steals your valuable items and then at the end you realise that *boom* you are robbed and the neighbors were right. It's just like the Devil controlling your emotions and intentions. And spoiling the good moments which you would value all your life. But if you just imagine that there is someone as the Devil who just wants to see your downfall then you will tend to see him as a competitor and you will always think twice you make a move. Cause if not God but this Devil is watching over you to see you fail miserably.
