William Farley from Outrageous Mercy
The cross demonstrates the permanent, immutable nature of God’s law. To save us, Jesus did not go around the law. He did not remove it. Rather, he fulfilled it. Taht is because the law is the eternal standard by which we will all be judged, and God is passionate about it. Every jot and tittle of the law must be fulfilled, promised Jesus (Matt. 5:17-20). The cross says, “There will be no lawbreakers in heaven.” The cross says, “God is fervent about his law.”
Verses such as “Now, by dying to what once bound us, we have been released from the law” (Rom. 7:6) have convinced many that law does not apply to Christians, that in some mysterious way it is no longer relevant or important. In one sense they are right. The law no longer enslaves Christians. We could not keep the law, so Jesus kept it for us. God has released all who put their trust in God’s Son from the burden of being perfect law keepers. But the cross reminds us that we will never be released from the law as the standard for judgment.
Jesus did two things on our behalf to fulfill the law. First, he lived a perfect life. He obeyed every jot and tittle of the law so that he could impute that obedience to to unworthy lawbreakers who put their faith in him. Second, on the cross he bore the punishment that lawbreakers deserve. Jesus glorified his Father’s passion for his law by both fulfilling it and atoning for its abuse.

Already Not Yet 
It’s refreshing to read this message from an evangelical Christian author. The last great message to a dying world as proclaimed in Rev. 14:6,7 seems to echo this idea when it hearkens back to a worship of Him who created the heaven, the earth, the sea and the springs of water — just like in the 4th commandment relating to the 7th day sabbath. If the commandments have not been altered, perhaps we’re missing something by ignoring the 7th day.
