We are not stoning the man.
We are correctly rebuking him for adultery which even Jesus said was grounds for divorce.
If we do not call evil by its true name, evil prevails.
It is evil to say because no person is sinless, we should not rebuke immoral acts. Moral people must rebuke adultery or we grant license to it.
Because lying is common, should we grant license to all manner of lying?
And, just which scripture grants you right to rebuke anyone?
Jesus did say adultery is grounds for divorce, in fact, the ONLY grounds.
But, where did he say that should a man commit adultery, he must be thrown out of any political office he may hold?
Holier than thou's are as sinful as anyone, whether they like to admit it or not. They might not have commited physical adultery, but can you honestly say you never looked at a member of the opposite sex in your entire lifetime in a lustful manner?
Didn't Jesus say that too was adultery, but of the heart?
Of course not. There is no excuse. There is also no excuse for adultery and I would never dream of 'excusing' Sanford for that. What I object to, and there has been much of it, is people who condemn him and take up ridiculous name-calling with such vehemence that it appears they would be more than happy to personally toss him into Hell.
What I saw in that press conference was a man who was confessing his sin and asking forgiveness. Was it under pressure? Sure, but who knows what sort of things result in conviction of the heart leading to repentance. Was he sincere? Only God knows that. Once someone has begun the process of seeking forgiveness and repentance it is incumbent upon the rest of the believing community so pray for and support that person seeking to restore them.
