Yahweh of the OT is the same Lord who is saving people in the New Covenant through the agency of the Holy Spirit. The same God is the minister of both the Old and New Covenants. there is liberty. Freedom from sin and the futile attempt to keep the demands of the law as a means of earning righteousness (cf. Jn 8:32–36 ; Ro 3:19 , 20 ).

There are two religious paths you can take. The way of the law and works that lead to destruction, or the way of life, through Jesus by faith in his perfect life of sacrifice and his resurrection, that leads to everlasting life. There is nothing he cannot over, if you surrender your life to him! Is this not good new, if you are suffering? He cares for his sheep, and leads them to green pastures. If you are lost, seek him and he will find you. Jesus is his name and there is no other.

When you give your life to Jesus, you are acknowledging, that you cannot earn you way to heaven, by following a bunch of rules (The Law). Your faith in Jesus, takes away any condemnation from the penalty of the Law.

Taken from John MacArthur Study Bible (Highly Recommend)

I have been crucified with Christ. See notes on Ro 6:2–6 . When a person trusts in Christ for salvation, he spiritually participates with the Lord in His crucifixion and His victory over sin and death. no longer I who live, but Christ lives in me. The believer’s old self is dead ( see note on Eph 4:22 ), having been crucified with Christ ( Ro 6:3 , 5 ). The believer’s new self has the privilege of the indwelling Christ empowering him and living through him ( see notes on Ro 8:9 , 10 ). gave Himself up for me. The manifestation of Christ’s love for the believer through His sacrificial death on the cross ( Jn 10:17 , 18 ; Ro 5:6–8 ; Eph 5:25–30 ).

Seek the Lord, in his word, and he will guide your ways.

Judgement was coming to the people, if they didn’t change their ways. Self-righteous doesn’t work. A changed heart, brings forth what is necessary. The fruit in the picture, is what flows from it. It is God, who must change the heart.

Beware of the legalism, that can so easily come upon us. God wants a changed heart, that compels us from within, to honor God, not some self righteous, me oriented, do good mentality that checks a box off. Jesus as God, showed us the Love, compassion and devotion to the Father, that he deserves, and we should desire. Thank you Jesus, for giving us your spirit, to help, and guide us, in our path.

For I delight in loyalty rather than sacrifice, And in the knowledge of God rather than burnt offerings.
