God allows defects (as we call them) and circumstances that shape our future. They are not our fault. How we respond to them and what we do with them, however, will predict our future.
We also determine our children’s future by teaching them how to respond to their circumstances.
As God predestines us, we also predestine our children.
"And he will restore the hearts of the fathers to their children, and the hearts of the children to their fathers, lest I come and smite the land with a curse." Mal 4:6
The goal of the Christian worker should be to restore hearts, specifically, the hearts of the fathers to their children.
When a child is exasperated by the father (Col. 3:21), a wedge is driven between the two. The curse to his child will be “moral impurity”. The son will be bound to immoral behaviors and the daughter will try to find a boyfriend who fulfils her desire for intimacy with her father.
Curse: Physically (as shutting in a net or trap, either literally or figuratively); usually a doomed object; a cursed thing, things which should have been utterly destroyed.
