For sin will have no mastery over you, because you are not under law but under grace.
[Rom 6:14 NET]
The secret of Moses’ failures was this: The law made nothing perfect, but the bringing in of a better hope did. And this was why his life work also came short of full realization. He saw but entered not the Promised Land. The founder of the law had to be its victim, and his life and death might demonstrate the inability of the law to lead any man into the Promised Land. The very fact, that it was for so slight a fault that Moses lost his inheritance, makes all the more emphatic the solemn sentence of the law. Cursed is every one that continueth not in all things that are written in the Book of the Law to do them.
But to the glory of the grace of God we can add that what the law could not do for Moses the Gospel did; and he who could not pass over the Jordan under the old dispensation is seen on the very heights of Hermon with the Son of Man, sharing His Transfiguration glory, and talking of that death on Calvary to which he owed his glorious destiny.
That grace we have inherited under the Gospel of Jesus Christ.
