From a pragmatic point of view, games and other vices separating the chaff from the grain are useful for the system. One less, more for the rest. God will punish those who have no love in them by taking time from them. On the other hand, everyone knows movies about zombie apocalypses, and these scenarios have nothing good about them. Some sound balance is needed.
A person is ready to do any stupid thing in the name of his love. The rage of love makes the entire world serve it. The world resists the rage of love but… it only makes it stronger. When it encounters a dam on its path, love accumulates its rage with joyful enthusiasm, thus acquiring a cosmic strength. The most important thing is to resist temptation and under no pretext (especially a good one) to leave the true path. The devil makes the chosen one go through fire and water in order to separate the chaff from the grain. The grain is true love and the chaff is false love.
To get rid of errors, you need to check, make and redo from 3 to 7 times. To get rid of random mistakes, you need to love your job. Love is a defense against chance. Chance is what separates the wheat from the chaff.
How to separate the wheat from the chaff? Very easy, grains courageous and brave and cowardly chaff. The tares will sink like flies in syrup, and the grains will rush towards the light of love and truth. The seeds will gain faith and give rise, and the tares will perish in the darkness of doubt. The grains will go to fear, and the tares will run from fear.
