Christians are not lawless or without law. We are alive not only the New Testament perfect law of liberty and its’ letter, but alive also to the Spirit of God that works that law in our heart.
Christians are dead to the Old Covenant law (the first 5 books of the Bible) which is done away (2Cor 3:7,11), commanded to be cast out (Gal 4:24,30), has been fulfilled and passed (Mat 5:17,18, Luk 24:44, Act 13:29), was and still is faulty (Heb 8:7,8), has decayed and waxed old back in the first century (Heb 8:13), was added until Christ (Gal 3:19), we are no longer under (Gal 3:24,25,5:18; Rom 6:14), has been taken away (Heb 9:1,18,10:9), has ended (Rom 10:4), and was only until John (Luk 16:16).
However, the Old Covenant was replaced with a better covenant (Heb 7:22), that has better promises (Heb 8:6), that has a better priesthood (Heb 7:12), with a better hope (Heb 7:19), we are now under the perfect law of liberty (Jas 1:25), the law of Christ (Gal 6:2) as is found in the New Testament scriptures.
The Old Covenant scriptures are still profitable for teaching, reproof, correction and instructions (2Tim 3:16), and offers us patience and comfort so we may have hope (Rom 15:4). The Old Covenant experience left the people in bondage to the law of sin and death (Rom 7:23). The Spirit of life in Christ set the converted free from the law of sin (Rom 8:2), as the law was weak and couldn’t deliver (Rom 8:3). You now – that are converted�- are freed from all the things which you couldn’t be freed from under the law (Act 13:39).
