I've always thought that who a person really is, is who they are in their home. This is because a home is made of people living under the same roof who are not normal like you. The people in your home, whether old or young, are different.
Differences attract - that's good. Maybe that's why you married the person you did. Differences also collide. Differences repel, like positive and negative magnetic poles. Differences conflict. A husband and wife are, in a few ways at least, polar opposites.
Conflict, therefore, is inevitable. Conflict is normal. If there's no conflict in your home, you have a problem. Probably, that problem is you. Or, at least, you are part of the problem. Always consider this possibility, for it reorients you on the road to being a peacemaker.
James van Yperen, in Making Peace, writes:
"Conflict reveals the true character of a leader. Jesus told His disciples, “You have heard that it was said, ‘Love your neighbor and hate your enemy.’ But I tell you: Love your enemies and pray for those who persecute you, that you may be sons of your Father in heaven…. If you love those who love you, what reward will you get? Are not even the tax collectors doing that?” (Matthew 5:43-46). Who we are is revealed by how we react to persecution." (p. 26)
If differences irritate you, that is your problem. If different approaches and styles "push your buttons," those buttons are yours. Own up to this and you are on your way to character formation.
