The government of grace thru the cross (death and resurrection with Christ) is supernatural and so much more efficient, powerful, restful, joyous and far less sinful than the economy of law.
Travis Bryan III writes:
The law counter-intuitively causes sin and sins to INCREASE. Rom 5:20; 7:12-24 (when the commandment came, sin revived); 1 Cor 15:56 (the strength of sin is the law) and Gal 3:19 (law provokes more sins). The law brings in the performance for acceptance principle (like a hamster on the wheel) which is always centered in the self and inevitably leads to comparison, competition and Phariseeical self-righteousness all of which is NOT the "righteousness of God." Rom. 10:1-4.
The cross kills the head of the octopus (sinful self) rather than merely fighting its tentacles (bad habits we try to rid ourselves of one tentacle at a time.) OCTOPUS TENACLES!"
The saints of Christ are justified freely by His grace and also blessed to be sanctified by His grace (divine enablement). Romans 3:24; 6:14
