It is startling but true: the decisions we make today don't simply affect ourselves; they effect our children and our children's children for multiplied generations. The Bible talks about how the iniquity of the fathers can be passed down for three or four generations. That means bad habits, addictions, negativity, wrong mind-sets and other types of iniquities can be passed down.
Perhaps you are struggling in certain areas right now because people who came before you made poor choices. Many times, you can look back and see the results of those choices somewhere in your family line. It is important that we recognize what has happened and that we not passively accept these negative patterns. Well, this is just the way I am. This poverty and sickness has been in my family for years.
No, you need to rise up and do something about it. It may have been years there for years, but the good news is it doesn't have to stay there. You can be the one to put a stop to it. You can be the one to choose the blessing and not the curse.
