I saw a married man with a single woman (not his wife) at one of those romantic hotels for couples. What's going on?

You were close enough to see if he had his wedding ring on? Did you see them kiss? What if it was his sister or Aunt coming for a visit and he was paying for her hotel room so she could be more comfortable in her own space and privacy? What if she said she didn't want to "put them out" so she will stay in a hotel room for the night? We have to be very careful how we perceive things. We should never gossip because our words can be deadly and can break up families. We should never assume. Just examine ourselves to make sure we are right before God.
