As you make your bed, so you must lie in it (one has to live with the consequences of one's actions, and one has to take the responsibility for them) — что посеешь, то и пожнешь

Example: "You think all the trouble you caused your mother will just disappear over night? You made your bed, now you have to sleep in it."

Note:
This variation is far more commonly used than [as you sow, so shall you reap].
