Read Isaiah 3
Focus on verse 10-11
The world is set up in a manner by which one typically ends up reaping what one plants. This is true of agriculture, as well as in the way we deal with people. We periodically use the phrase “they had it coming to them” when someone receives back what they have been dishing out. This principle tends to be true of both good and evil.
Isaiah is delivering the word of the Lord to the people of Judah when he writes, “Tell the righteous it shall be well with them, for they shall eat the fruit of their deeds. Woe to the wicked! It shall be ill with him, for what his hands have dealt out shall be done to him.” (Is. 3:10-11) It would seem this is a principle that God has instilled in His creation. It is also somewhat comforting to know that God sees fit to bring justice upon those who do evil things by allowing them to reap what they have sown, while the righteous also reap what they have sown.
