LS98,
When someone doesn’t obey the commands of Christ, but claims she is a Christian, she is either living a carnal life of disobedience or isn’t really a Christian.
I expect a Christian would follow Christ’s commands. I expect a non-Christian to act like a non-Christian. I was one.
In this instance, I cannot know this poster is a believer by their choices. It seems a kinder assumption all round to assume they are a non-believer and expect a lower standard. If they need to know the Savior, I can only pray they come to know His grace. If it turns out they know the Savior, their lives will reflect this.
I would hope that a person, who is trying to follow Christ's commands, would do some research to see if those 'commands' REALLY come from Christ!
