You reap what you sow

You reap what you sow.  If you sow havoc and discord, you reap havoc and discord.  If you sow envy and jealousy, you reap envy and jealousy.  Everything you do comes back to you.  “Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap.” (Galatians 6:7, KJV)  Therefore, take care of how you treat others, because that same treatment will be repaid to you in your lifetime.  What you do now comes back upon you later.
