ObjectiveTRuth ...OP "mosaic law still valid" ?
Scriptures (NT) tells us Jesus fulfilled all of the mosaic law and susequently he inherited all of the blessings. He became the source of these blessings to the world as the nation of Israel failed to do. 70 AD confirmed that the sacrificial and creamonial laws was ended since Jerusalem was destroyed as history confirms.
The only obligations we have as Christians is the moral law as summed up in the 10 commandents, NOT as a condition for gaining salvation but as a result of our new nature that enables us to overcome the sin problem within.
No system of laws and jails and punisment can change our nature or warrant the gift of eternal life. We are freed FROM SIN NOT FREED TO SIN !
My 2 cents ;)
