What is the difference between Judaism's law keeping and the grace of God?
Judaism is characterized by rules, regulations, law keeping, and Phariseeism, while God's grace gives salvation freely, without works and without lifting a finger. That contrast flies in the face of human thinking. Grace begins when a person admits they can do nothing, believes the Lord has done it all, including His death and resurrection, and then serves.
Les teaches that Saul of Tarsus, later Paul, had been saturated with Judaism—a Hebrew of the Hebrew, a Pharisee of the Pharisees, educated at the feet of the greatest Rabbi of that time, and more religious than many peers. Les says it took time for that system to be cleansed from him by the power of God. The stark difference is that Judaism is all rules, regulations, law keeping, and Phariseeism, whereas stepping into God's grace means receiving everything free for nothing, without lifting a finger, which offends human thinking. Salvation begins when a person tells the Lord there is nothing they can do, believes He has done it all, died for them, and rose from the dead. After that, God expects believers to move out and live a life of service, not simply rest in saving grace and do nothing.
