The king of Judah, Jehoshaphat, was a good king. But he made a bad decision. He joined his family with the family of Ahab. Then the whole kingdom of Judah suffered for many years.
Sometimes when we sin, our sin causes other people to suffer. There are always earthly consequences for our actions. Often we say hurtful things to other people. It may take a long time for the hurt to go away. When we lie, people may not trust us any more. When we choose to put alcohol and drugs into our body, we may become addicted to those things.
The bad things we do always cause pain for us and for other people. But we can praise God that He gives us His grace through Jesus! Jesus saves us from being punished for our sins. Jesus even helps us heal the earthly consequences of our sins. And, the Holy Spirit helps us so we can decide not to do bad things (1 Corinthians 10:13). Praise God!
