All of a parent’s children are their heirs, but their children from their first family are their primary heirs. In many cases, adultery creates situations where the children of the first family are completely eliminated as heirs. Lawyers will tell you that it is determined by the person with whom the parent currently lives. A second spouse will want to be first, especially if they were successful in persuading the parent to move in with and live with them. Many will demand that the children of the first family be completely eliminated in order to make room for the children of the second family.
Children of the second family must understand that their salvation is not in the abundance of things and that covetousness will not get them to heaven. Children of the first family, do not hire a lawyer to fight them. Just remember that the second family is focused on things that have little to do with their salvation. The first family is very important to God!
And one in his company said unto Jesus, “Master, speak to my brother, that he divide the inheritance with me.” And he said unto him, “Man, who made me a judge or a divider over you?” And he said unto them, “Take heed, and beware of covetousness for a man’s life consisteth not in the abundance of the things which he possesses.”(Luke 12:13-15)
