The promises and blessings of God have all been fulfilled in Christ. In Christ, we don't then turn to the law to find the blessings that were promised there. We look solely to Christ, who is our all in all, in Whom we have everything!
2 Cor 1:20-22
For all the promises of God in Him are Yes, and in Him Amen, to the glory of God through us. Now He who establishes us with you in Christ and has anointed us is God, who also has sealed us and given us the Spirit in our hearts as a guarantee.
Christ has redeemed us from the curse of the law,
having become a curse for us (for it is written, "Cursed is everyone who
hangs on a tree"), that the blessing of Abraham might come upon the
Gentiles in Christ Jesus, that we might receive the promise of the
Spirit through faith.
Now to Abraham and his Seed were the promises made. He does not say, "And to seeds," as of many, but as of one, "And to your Seed," who is Christ. And this I say, that the law, which was four hundred and thirty years later, cannot annul the covenant that was confirmed before by God in Christ, that it should make the promise of no effect. For if the inheritance is of the law, it is no longer of promise; but God gave it to Abraham by promise.
Blessed be the God and Father of our Lord Jesus Christ,
who has blessed us with every spiritual blessing in the heavenly places
But now He [Jesus] has obtained a more excellent ministry, inasmuch as He is also Mediator of a better covenant, which was established on better promises [than the Old Covenant - the Law]. For if that first covenant [the Law] had been faultless, then no place would have been sought for a second.
2 Peter 1:3-4
His divine power has given to us all things that pertain to life and godliness, through the knowledge of Him who called us by glory and virtue, by which have been given to us exceedingly great and precious promises, that through these you may be partakers of the divine nature…
1 John 2:25
And this is the promise that He has promised us — eternal life.
