The family is the context in which Christians learn to experience God the Holy Spirit. It is within the family that Christians learn how to be loved, corrected, taught, encouraged, and provided for; if we never recieve such input and direction from our community, we will not recognize it when the Spirit does it. If an individual is consistently receiving such edification in the family, he will recognize the Spirit’s work more easily when he is alone.
When an individual knows the Spirit’s work in his life, he is able to mimick that work in the context of his family. It is a cycle entirely enabled and powered by the Holy Spirit. Take that and chew on it.
