In a secularized and ungodly workforce, Christians do need to stand up for themselves, unless they have obtained the mother of all virtues: humility. I will give you an explanation from the desert fathers.
A monk was in the desert. He had a small hut with a few small things. Thieves came upon him and beat him up. He prayed in the corner as they took his belongings. Then he noticed that they forgot a small flask that was left on the doorframe. So he ran after them, carrying the flask. not to ask them for his stuff back, but to say ‘hey! You forgot this!’ They were surprised by his humility and gave him his stuff back and became his disciples, saying ‘This truly is a man of God.’
This wouldn’t work for most people, as despite how much you mostly like to say it, most of you do still spit in the face of God. In fact, you mostly all spit in the face of God! The last Saint died back in the 19th century, when these holy miracles happened! So go on, stand up for yourself!
Enter hell with all humility, if only to get a reduced sentence from Jesus.
