This topic is a good one and the one I have seen happening everywhere. When we elaborate on the sins of the parents, it means what the parents have committed in one way or another that would turn out to affect the child or children at the end.
A case happened in my area where a boy was rejected of a job he was qualified for. Ordinarily, the boy has all it takes to get the job and even passed their test more than others. It happened that one of the employers knew the boy's father when he was still alive. He knew what he had been doing and what killed him. He has to relate the issues to others as well as the superior. Although the superior was ready to give this boy the job after seeing his performance, the traitor in the house related the issue to the superior. Meanwhile, the boy has been told that he was qualified for the job and has the best result. He was so happy, but after waiting for some time, they brought him a paper. He thought it was an appointment letter. When he got home, he opened it and found out that it was a letter to halt his job. He cried, but then had no one to put the blame on except the late father.
In my community, there is a law binding all married women. It has been put in place by our forefathers and has been working seriously on the married women. Anyone who cheats on her husband with another man will fall sick until she confesses her sins. And when she fails to confess, she would die after living for days or a few weeks. Now, that was supposed to be better, but then since she refused to talk, the children would be the ones suffering for what they had not committed. Her sins would be transferred to her children. The first son will first fall sick and, if not detected on time, would die. It will also be transferred to the second child until the last one is gone. But somehow, the elder of the family would go out searching for what the problem might be. When he's done carrying out his findings, the ritual has to be carried out, which in turn would free the children from untimely death.
Carrying the sins of the parents to the children is something not worthy. Personally, I don't like that act, except when the child is like the parents who do not want to change. Most children have the ability of the parents. They want to be like their parents and want to do what they are doing.
I have seen a boy whose dad was a thief. He grew up to become a thief. This means the dirty blood of the father was already flowing in him.
Suffering from the sins of your parents would make you lose countless opportunities. As you grow up, you will become lonely just because of what your dad has done in the past.
In conclusion, just because my father or mother has sinned does not mean I will also sin. My parents are thieves, which does not mean I will grow up to become a thief.
