3:6 persecuting the church. It is significant that Paul had considered his zeal in persecuting the church as a highly meritorious service to his religion. It seems always to be true that those who are devoted to some false religion are the most zealous opponents of true Biblical Christianity.
3:6 blameless. If anyone could ever have been saved by keeping the law, it would have been the Apostle Paul. Yet he came to regard all his “righteousnesses” as “filthy rags” (Isaiah 64:6) when he saw Christ as He is.
