That's not what the New Testament teaches
The NT does not contradict
Jeremiah 31:33), but rather it quotes it in affirmation that the New Covenant still involves following the Law of Moses (
Hebrews 8:10).
following the law of Moses is what led to the Galatians being "bewitched" turning away from follow Jesus and back to following the law of Moses causing them to lose their salvation
Galatians 5:4
Christ is become of no effect unto you, whosoever of you are justified by the law; ye are fallen from grace.
Christ spent his ministry teaching his followers to obey the Law of Moses by word and by example, so Galatians should not be interpreted in a way that turns it against being a follower of Christ. God wanted His children to repent and to return to obedience to the Law of Moses all throughout the Bible and even Christ began his ministry with that Gospel message (
Matthew 4:15-23), so it would be absurd to interpret
Galatians 5:4 as Paul warning against doing that and saying that we will be cut off from Christ if we repent and believe the Gospel of Christ. Likewise, it would be absurd to interpret
Psalms 119:29-30 as if he wanted God to be gracious to him by teaching him to fall from grace, so you are not correctly identifying what Paul was speak against.
In Deuteronomy 13, the way that God instructed his children to determine that someone is a false prophet who is not speaking for Him is if they speak against obeying the Law of Moses, so it is either incorrect to interpret Paul as doing that (my position) or he was a false prophet, but either way followers of Christ should follow his example of obedience to the Law of Moses. If you agree with me that Paul was not a false prophet, then you should be the first to object to you interpreting him in a way that makes him out to be one.
People need to understand we are now under the Law of Christ and the OT law is not longer applicable.
People get confused because God's moral law was in place before the OT law was ever given, iot was included in the OT law, and it is also included in the Law of Christ under the New Covenant.
Again you have given no justification for thinking that the Law of Christ is something other than or controversial anything that Christ taught or anything that has come from the mouth of God. God is not in disagreement with Himself about which laws we should follow but rather the Law of Christ is the same as the Law if the Spirit and the Law of the Father, which was graciously given to Moses.
The existence of the category of moral law would imply that we can be acting morally while disobeying the laws that aren’t in that category, but there are no examples in the Bible where disobedience to any of God’s laws is stated to be moral and I see no justification for thinking that it can ever be moral to disobey God. Morality is in regard to what we ought to do and we ought to embody God’s likeness through being a doer of His character traits, so all of God’s laws are inherently moral laws. Legislators give laws in accordance with their understanding of what ought to be done, so to claim that some of God’s laws are not part of the moral law is to claim that God made a moral error about what ought to be done when He gave those laws and is therefore to claim to have greater moral knowledge than God. You have a disagreement with God about what ought to be done and you are taking the position that you should lean on your own understanding of morality by only doing what is right in your own eyes rather then that trusting in God with all of your heart to correctly divide between right and wrong through His law (
Proverbs 3:1-7).
God’s character traits are the fruits of the Spirit and the Law of Moses was graciously given in order to teach us how to be a doer of His character traits, which is why the Spirit has the role of leading us to obey the Law of Moses (
Ezekiel 36:26-27). In
Romans 8:4-7, Paul contrasted those who walk in the Spirit with those who have minds set on the flesh who are enemies of God who refuse to submit to the Law of Moses.
In the New Testament, many mentions of “the law” is actually referring to Law of Christ (aka the Law of Liberty) and is not talking about the old testament law. Christians are NOT called to keep or live under the old testament law, but we ARE called to live under the Law of Christ.
The Law of Moses is perfect (
Psalms 19:7), it is of liberty (
Psalms 119:45), and it blesses those who obey it (
Psalms 119:1-3), so when
James 1:25 speaks about the perfect law of liberty that blesses those who obey it he was not saying anything about the Law of Moses that wasn’t already said in the Psalms.
To them that are without law, as without law, (being not without law to God, but under the law to Christ,) that I might gain them that are without law.
That uses a parallel statement to equate not being without the Law of God with being under the Law of Christ, which completely undermines your position that the Law of Christ is something other than or contrary to anything that God has spoken.
The goal of everything that God has spoken is to teach us how to partake in the divine nature and God has not spoken anything that was not in accordance with the divine nature.
In John 17:17, it says to sanctify them in truth and that God’s Word is truth, which is in accordance with the Law of Moses being truth (Psalms 119:142) and contrary to your position. If you agree that we have been called to holiness, then you should be arguing in favor of following God’s instructions for how to be holy as He is holy rather than arguing against doing that.
If you agree that we should be in God’s image, then you should be arguing in favor of following God’s instructions for how to do than rather than against following them.
If you agree that we should know God and obey the Gospel, then you should be arguing in favor of following God’s instructions for how to do that rather than against following them.
