The phrase "you reap what you sow" is a proverb that means future consequences are inevitably shaped by present actions. It is derived from Galatians 6:7 in the Bible, which states "Be not deceived, God is not mocked: for whatsoever a man soweth, that shall he also reap". The proverb emphasizes the idea that the results of ones actions are directly proportional to the effort and good or bad intentions put into them.

In other words, if you do good things, you will get good results in the future, and if you do bad things, you will get bad results in the future. The proverb is often used to encourage people to make good choices and to warn them of the consequences of their actions. It is a reminder that we are responsible for our own actions and that we must take responsibility for the outcomes of those actions.
