Yes! Christ paid the penalty. Yes! We are free from the penalty of the Law. But where are we told we are free from no longer trying?
Any insight, once more, Biblically?
I wouldnt say we are free from 'trying' because the mosaic law shows us Gods standards. They are beneficial for us in that we can determine how God views certain matters. But you have to realise that the mosaic law was only applicable to the Jews because they agreed to be joined to God under a very specific covenant which included 'applying' those laws. Exodus 19:5-6 Exodus 19:7-8
Christians were never invited to be under that covenant. They were invited to be joined together under the 'new covenant' which Jesus instituted with his Apostles Luke 22:29. This new covenant was prophesied by the prophet Jeremiah 31:31-34
By instituting a new covenant as a means to be joined to God, it shows us that the mosaic covenant had been replaced.
the new covenant did not require sacrifices because Jesus gave a sacrifice for sin which was far more valuable then any animal sacrifice was. the death penalty of the mosaic law was also not binding on christians which made forgiveness of sins possible without sacrifice. We can simply ask God to forgive our sins and he does whereas if you are under the mosaic law you would be required to give a blood sacrifice...if you did something really bad, you would have to give your own life.
Check out Pauls explanation at Hebrews chapters 8&9
Hebrews 8:6 But now [Jesus] has obtained a more excellent public service, so that he is also the mediator of a correspondingly better covenant, which has been legally established upon better promises.
Also just think about this.. Abraham did not live by the Mosaic laws, nor did the men of faith of old such as Noah or Able or Enoch....yet all were considered righteous by God. You see, following a bunch of laws does not make one righteous...its our attitude toward God which makes us acceptable to him. That is why faith in Jesus is what puts us in line for salvation...our attitude toward Gods provisions and promises is how he judges us by - not by how many laws we perfectly abide by (which we cannot do anyway, so God is really making things easier for us)
