Proverbs 29:21 He that delicately bringeth up his servant from a child shall have him become his son at the length.
This verse can seem to refer to if a child comes into someones life at an early age and is around you so much that it like they are part of the family, then you think of them as family. This could refer to foster parents who take children in a very early age and have a long tome that they actually become part of the family and could even eventually be adopted into the family. Think back over the children’s lives you have affected to the point where they treated like family at your home and were you a good influence on them that lead the min the right direction. Even relationships as children with other children growing up where you spend so much time together that it seems as if you are part of the same family. There is bond here that as Christians we should strive to obtain with everyone we come in contact with so they can become a part of our heavenly family.
