“A false balance is abomination to the LORD: but a just weight is his delight.”
Some people call it karma but if you constantly try to screw people or judge them unfairly you will get yours.
Matthew 7:1-3 tells us:
“Judge not, that ye be not judged. 2 For with what judgment ye judge, ye shall be judged: and with what measure ye mete, it shall be measured unto you. 3 And why beholdest thou the mote that is in thy brother’s eye, but considerest not the beam that is in thine own eye?”
Remember get your own stuff straight before you suggest to others how to straighten theirs.
