we frum yidden believe in Torah SheBal Peh there are hundreds of Rishonim and Achronim who explaim all these situations in ways you probably wouldn’t even understand. It’s a bit hard to explain things through writing in a forum like this but I seriously recommend that you go to a rav and have these things explained to you Al Pi Hashkafas Hatorah!

Rabbi of Berlin I’m not sure what so hard about understanding that people’s nisyonos are on different levels. as you climb in your avoidas Hashem your nekudas habechirah changes and things that may have been difficult till now are not a nisayon anymore, and that doesnt make you any less human. so saying that the yetzer hara of the avos was different than yours just means they were greater tzaddikim than you. Does that sound too close to apikorsus too? If you still don’t get it then i give up!
