If you tell someone something that is offensive to them, but that they need to hear, you are going to appear offensive. How do you think the Jewish leadership felt about Peter, John, and Stephen? I bet they found them, personally and not just the message, offensive.
But were they really being offensive? I don't think they were. And yet if they were to appear on this board and preach they way they preached in Acts they wouldn't last a day before they were banned.
This is:
1) Technically incorrect (since neither of them save anybody)
2) Incorrect "in spirit" since Mack's efforts here are absolutely NOT without merit/value. And (IMO) "you'regoingtoHe!!andneedtogetsaved!" postings without any relationship are detrimental to the cause of Christ... not aiding it.
3) Scripturaly unsound. "So then neither is he that planteth any thing, neither he that watereth; but God that giveth the increase." It also goes against the later half of 1Cor 12.
Their posts were offensive AND had nothing to do with "I can't help it, that's what the Bible says"
