Ok, a little more time to try and explain the Law question.
Christ was the fulfillment of the Law through His birth and death and especially rising from the dead, as explained by others here, but it goes deeper than that.
As also explained by others Christ also set new laws into place as well as explained their value for mankind, but most especially showed through His Acts and Actions the proper path to salvation.
It goes deeper than a simplistic view of just walking His walk or the popular view that one should believe in Him as their personal savior. This view is what mainstream Christian religion would have you believe, and that is ok for those who don't mind being led by the nose, who must have some sort of assemblage or church or symbol to believe in, but it misses the mark and places too much power in those man made ins utions. Many of His apostles warned against this. In fact they went so far as to chastise many of the church leaders of the times for misusing and misleading to gain personal power in the name of Christ, rather than spreading the Word.
The Word was that He had come, fulfilled the Laws of the OT, arose from the dead and erased original sin. But He commanded us to follow in His footsteps. He promised that those who did as He did, would not only do the things He did, but do even greater things than He did.
In other words, if you live your life as a personification of Christ, or as closely as you can, exemplify Christ, or better yet, be a Christ like example through your everyday ACTIONS then Christ will begin to work through you.
If you reflect Christ, then in essence, you are Christ and Christ is you. You rise above your earthly desires.
This is saying a lot in a simplistic manner because it means a lot.
For example, Christ was never poor in the earthly sense, nor was He an egotist throwing around a superior persona, nor was He sickly, nor was He ignorant, nor was He greedy, nor did He wage war, nor was He jealous, or prideful, or desirous of anything more than the love of the Father. He walked the talk, and that talk was love and forgiveness which was His new commandment to mankind. To do this is not easy, but worth it because it leads straight to the Father.
And it even extends to life on earth in that a person who is Christ like will never know sickness, want, hunger, or even death, even in a literal sense.
All of these teachings were explained in His parables. Unfortunately many of His followers (or brothers as He called them so as to not set Himself up as being better than them) misunderstood. They could not accept these simple truths because they had so little faith, because their lives were beset with pains, illness, poverty, enemies, etc.
But the truth was it was all in their minds, they, having free will, had created their own misery. The Father never created their misery, rather He allowed them to create it. We still do, even now.
Christ's Law is that once we reflect His Way and seek the Father, then all of us become Christ ourselves, Christ becomes us, and then poverty, sickness, and contentiousness will disappear in our lives, and we will even conquer death.
It is spiritual in nature first, but the new Law is that it filters down and becomes reality physically, emotionally, and mentally.
You are all welcome to believe whatever you want of this. I have tried to explain it in as simplistic a manner as possible.
Jesus used parables for the most part because it is so hard to believe, even to this day. It literally takes a suspension of belief sometimes in order to accomplish. It seems like fairy tales, but it is Truth.
Yet Christ did it in His day, and said we all would be able to do it too, if we followed His example, because we all are also Sons of the Father just as Jesus is, thus co-heirs to the kingdom of the Father. Thanks to Jesus Christ, we are all co-creators in and of life too.
We all limit ourselves by our beliefs, God does not limit us, He gave us free will, because our beliefs are literally who we are, who we were, and who we will become. What you believe, so will it be. And all you need is faith no bigger than a mus seed.
I Am That I Am
