Judge not, unless we be judged, so the Good Book says. One who condemns another to hell is usually on the path that already leads there. This is not to say we can’t know someone by the their works. The bible defines sin, we must preach against sin, and instruct all to turn from sin. However, we can’t punish anyone for committing sin. It is God who judges sin, and ours turn from it.
