If all Scripture is profitable, why don’t we use the Old Law?

Answer:

"All Scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness, that the man of God may be complete, thoroughly equipped for every good work" (II Timothy 3:16-17).

All Scripture, Old and New Testament comes from God. The Scriptures teach us what is right (doctrine), what is not right (reproof), how to get right (correction), and how to stay right (instruction). However, it can only do this if kept in its proper context. "Be diligent to present yourself approved to God, a worker who does not need to be ashamed, rightly dividing the word of truth" (II Timothy 2:15).

The Old Testament has its purpose. "For whatever things were written before were written for our learning, that we through the patience and comfort of the Scriptures might have hope" (Romans 15:4). It is a rich source of examples, both good and bad.

"Moreover, brethren, I do not want you to be unaware that all our fathers were under the cloud, all passed through the sea, all were baptized into Moses in the cloud and in the sea, all ate the same spiritual food, and all drank the same spiritual drink. For they drank of that spiritual Rock that followed them, and that Rock was Christ. But with most of them God was not well pleased, for their bodies were scattered in the wilderness. Now these things became our examples, to the intent that we should not lust after evil things as they also lusted. And do not become idolaters as were some of them. As it is written, "The people sat down to eat and drink, and rose up to play." Nor let us commit sexual immorality, as some of them did, and in one day twenty-three thousand fell; nor let us tempt Christ, as some of them also tempted, and were destroyed by serpents; nor complain, as some of them also complained, and were destroyed by the destroyer. Now all these things happened to them as examples, and they were written for our admonition, upon whom the ends of the ages have come. Therefore let him who thinks he stands take heed lest he fall" (I Corinthians 10:1-12).

None of this changes the fact that the law which we live under today is the Law of Christ. God said that the law would be changing and it did.

"But now He has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises. For if that first covenant had been faultless, then no place would have been sought for a second. Because finding fault with them, He says: "Behold, the days are coming, says the LORD, when I will make a new covenant with the house of Israel and with the house of Judah-- "not according to the covenant that I made with their fathers in the day when I took them by the hand to lead them out of the land of Egypt; because they did not continue in My covenant, and I disregarded them, says the LORD. "For this is the covenant that I will make with the house of Israel after those days, says the LORD: I will put My laws in their mind and write them on their hearts; and I will be their God, and they shall be My people. "None of them shall teach his neighbor, and none his brother, saying, 'Know the LORD,' for all shall know Me, from the least of them to the greatest of them. "For I will be merciful to their unrighteousness, and their sins and their lawless deeds I will remember no more." In that He says, "A new covenant," He has made the first obsolete. Now what is becoming obsolete and growing old is ready to vanish away" (Hebrews 8:6-13).

From the time God announced through Jeremiah in Jeremiah 31:31-34 that there would be a new law, the Old Law was under a "death sentence." "Therefore, my brethren, you also have become dead to the law through the body of Christ, that you may be married to another -- to Him who was raised from the dead, that we should bear fruit to God" (Romans 7:4).

The Old Law is there to help us understand the law that we live under, but it isn't the source of our law in this age.

"Stand fast therefore in the liberty by which Christ has made us free, and do not be entangled again with a yoke of bondage. Indeed I, Paul, say to you that if you become circumcised, Christ will profit you nothing. And I testify again to every man who becomes circumcised that he is a debtor to keep the whole law. You have become estranged from Christ, you who attempt to be justified by law; you have fallen from grace" (Galatians 5:1-4).

"But he who looks into the perfect law of liberty and continues in it, and is not a forgetful hearer but a doer of the work, this one will be blessed in what he does" (James 1:25).
