Torah is for the criminal... The lawless ones. Those who sin. It is there to show what sin is.
We are no longer obligated to obey it to maintain a right relationship with God because that's not how a right relationship with God is maintained under the new covenant.
But if we love YHWH, we will keep his commandments. And His commandments are not grievous.
All the blessings and curses of the OT do not apply to born again believers because God is dealing with people in a new way, the way of Christ, instead of the old way with the letter of the Law.
No, the curses do not apply. There is nothing that says the blessings don't remain.
It's no longer *If you do this, then I'll do that.*
Oh, but yes, it is - The ONLY thing that stands between you and destruction is a covering of the 'Better Blood'.
NOW it's grace and mercy, us being seated in the heavenly places in Christ Jesus, the Holy Spirit in us, who is the guarantee of our redemption until we acquire possession of it, that we are washed and cleansed and forgiven, having the righteous requirements of the Law met for us and in us by virtue of the fact of being in Christ, being credited to our account.
It has always been about grace and mercy. And if we love YHWH, we will keep his commandments.
If, according to you, the Torah can never change, then why aren't those curses still applicable today?
What you continue to defend is your version of what "obedience" to Jesus' commands really mean. Though Jesus ratifies every one of the Ten Commandments - imposing their spirit over the letter, we do not find Him doing the same for the 603 OTHER components of the Mosaic Law. There's a reason for that. Jesus is our righteousness - He fulfills ALL righteousness in our place - and it is why we are also justified THROUGH faith in Him, our Redeemer. So, yes, Jesus DID say if we love Him we will obey His commandments and that His commandments are not "grievous". He also said ALL the commandments could be summed up in, "Love the Lord your God with all your heart and with all your soul and with all your mind.’ This is the first and greatest commandment. And the second is like it: ‘Love your neighbor as yourself.’ All the Law and the Prophets hang on these two commandments.” (Matt. 22:37-40)
If we obey this with all our hearts - through the indwelling power of the Holy Spirit, we will be demonstrating we are His disciples and that we love Him.
