The law came through Moses, grace and truth came through Jesus Christ. Learn how Jesus Christ fulfilled the Law.
John 1:16-17 New King James Version (NKJV)
16 And of His fullness we have all received, and grace for grace. 17 For the law was given through Moses, but grace and truth came through Jesus Christ.
In his sermon on the mount, Jesus declares that the Law must not be destroyed, but fulfilled.
Matthew 5:17-18 New King James Version (NKJV)
17 “Do not think that I came to destroy the Law or the Prophets. I did not come to destroy but to fulfill. 18 For assuredly, I say to you, till heaven and earth pass away, one jot or one tittle will by no means pass from the law till all is fulfilled.
The expression, “The Law” is often misunderstood. In the Old Testament, the law came after their deliverance. From Exodus 19:1 we see that the Law of Moses was given three months after the Red Sea Crossing. God delivered his people before the Law was in place. Salvation came before the Law.
Exodus 19:1 New King James Version (NKJV)
19 In the third month after the children of Israel had gone out of the land of Egypt, on the same day, they came to the Wilderness of Sinai.
The Law was mediated grace. Moses as the mediator was a type of Christ.
Jesus is embodied grace. Jesus Christ, God in the form of a man came, put himself on the cross at Calvary, went in and defeated the enemy, our adversary called the devil, came back out, ’cause he got born again, ascended to the right hand of the Father and then released the power of the Holy Spirit who dwells inside the believer’s spirit.–That’s embodied grace.
Grace is inside of you. So it supersedes the old Law which was mediated grace.
