In this message, we learn that hidden sin was the cause of Israel's tragic defeat at Ai. Achan stole some of the war plunder that was to be devoted for destruction and so brought judgement on himself and Israel. In the same way, sin in our lives and in our nation brings God's judgement on the sinner and on the nation. The hidden sin of abortion has led to the murder of 60 million babies since the passage of Roe v Wade in 1973. The resultant moral decay in our nation since that time is part of God's judgment on America. Only repentance and the election of godly leaders who will remove that sin will allow this nation to be blessed again.
