It is easy to recognize that a father influences his child. That’s one generation influencing the next, but a grandfather or great-grandfather also influences his grandchildren or great-grandchildren either directly or indirectly. The power of fatherhood is transgenerational.
A grandfather or great-grandfather may have an opportunity to directly influence his grandchild or great-grandchild, but regardless, he has had a powerful influence indirectly, because he has helped raise the grandchild’s father or mother or the great-grandchild’s grandfather or grandmother.
As a father’s influence becomes more indirect, it also becomes more widely felt. There is a reason we call genealogies a family tree. From two people come many branches — that is the widening of influence. Families grow by multiplication not simple addition.
The Bible recognizes this influence of one generation upon another.
He established a testimony in Jacob and appointed a law in Israel, which he commanded our fathers to teach to their children, that the next generation might know them, the children yet unborn, and arise and tell them to their children, so that they should set their hope in God and not forget the works of God, but keep his commandments; and that they should not be like their fathers, a stubborn and rebellious generation, a generation whose heart was not steadfast, whose spirit was not faithful to God. (Psalm 78:5–8, ESV)
Psalm 78 recognizes the transgenerational power of fatherhood. This influence may be for better or worse. The psalm advocates the influence for the better, but it illustrates the influence for the worse.
Stu Weber in his book, Tender Warrior, quantifies a father’s spiritual influence.
When the father is an active believer, there is about a seventy-five percent likelihood that the children will also become active believers. But if only the mother is a believer, this likelihood is dramatically reduced to fifteen percent.*
What kind of influence do you want to have on the generations to come?
Fathers, do not provoke your children to anger, but bring them up in the discipline and instruction of the Lord. (Ephesians 6:4, ESV)
