When I read about hatred like this, it is no wonder to me that Believers have a bad name.
Regardless of your feelings on the issue, Scripture teaches love, never hate. If you find yourself disagreeing with a lifestyle choice, then disagree, but articulate why you disagree. Discuss it. Seek to understand, then to be understood. But we must never, never hate.
What’s more, we cannot confuse the people with the action. Every person has priceless value, because we are created in His image. We can all find things that someone else does that we see as bad, but that doesn’t mean that the person is bad. What we do is not who we are. The father of this family, I imagine, wants nothing to do with God, because he’s been presented with an image of God that is a hateful bigot. Nothing could be further from the truth.
If Believers are to be intolerant of something, then let us be intolerant of hate. And let’s do so before we all have to answer for the bigotry of a few.
