Mark 10:9 And no one should separate a couple that God has joined together.

Can a person really separate two other people, like a married couple or friends that were once close?

You betcha.

All it can take is a little negative comment like, "I can't believe she did that to you." Or, "Should he be saying that?"

This is different from genuine concern one friend to another should they see something unhealthy happening in a marriage or friendship. This is butting in and planting seeds of doubt and mistrust because they happen not to agree with someone's approach, or are jealous of the relationship others have.

This verse in Mark shows how seriously God considers the actions of people who try to tear apart what He has brought together. I believe this principle can apply beyond marriage.

Be attentive to the times when one friend tries to influence you negatively toward another. Stop that type of activity right away. You can be friends with more than one person at a time. You don't have to spend all your time with one individual. Jesus didn't.

Pay attention, too, to those who would instigate you to complain about your spouse. Avoid talking down about your spouse to others so they will know that type of conversation is not something you tolerate.

Same thing with family members, kids, etc. If there's a problem, address it. Get godly advice even. But if the person you are talking with isn't part of the problem, or the solution (which may mean give godly, discreet counsel), then keep your comments uplifting.

No one should separate what God has joined together. That applies to lots of relationships.
