You've made your bed, and now you have to lie in it.
Meaning: You have to suffer the consequences of the bad situation for which you are responsible.
Isaiah 28:20
For the bed is shorter than that a man can stretch himself on it: and the covering narrower than that he can wrap himself in it.
Galatians 6:7 Be not deceived; God is not mocked: for whatsoever a man soweth, that shall he also reap. 8For he that soweth to his flesh shall of the flesh reap corruption; but he that soweth to the Spirit shall of the Spirit reap life everlasting.
