You’re responsible for defining and exposing sin in your family as a part of your leadership, but your relationship with your wife is at least as important as your position in defining sin. Maybe more so.
We find a great deal to think about this in the clear teaching the apostle Paul gave about “the weak” and “the strong.” In the book of Romans, when discussing what foods were okay (or “clean”) for a Christian to eat, he acknowledged that “disputable matters” would be normal in the Christian community. As you read his words, think about how they are just as true in a Christian marriage:
Accept him whose faith is weak, without passing judgement on disputable matters. One man’s faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables, The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. (ROMANS 14:1-3)
