That is true in one sense but false in another. True because persona's rub off on each other, there is the expression, "you are what you date" but its false because everyone makes there own choices. I have spoken to people that have partners that do not agree with there views. Opposites attract in some cases.I have come across this expectation a number of times.
it goes something like this, If a husband obeys God in being a husband
it will somehow cause a wife to obey God in being a wife.
But how does the obedience of one person to God have anything to do with the disobedience of another.
