This is not a fact but an almost impossible act to follow. It's like trying to touch the horizon. You can't. But you have a path to follow, a direction the needle of your inner compass will point to... Some people have it naturally, others need guidance and a reminder why they are more than a animal, IF they chose to...

Same with judging. you cannot NOT judge at every moment, every time you breathe... Since those "orders" are impossible to follow to the letter, being the nature of human we will forever be sinners... I haven't open a bible in centuries but that is how I interpreted it.... I could be wrong, of course.
