By the Testimony of the Messiah they can.. from stone tablets to our inwards... by the Grace of GOD through Faith.
The veil was ripped when the Messiah ...
Matthew 27
48And straightway one of them ran, and took a spunge, and filled it with vinegar, and put it on a reed, and gave him to drink. 49The rest said, Let be, let us see whether Elias will come to save him. 50Jesus, when he had cried again with a loud voice, yielded up the ghost. 51And, behold, the veil of the temple was rent in twain from the top to the bottom; and the earth did quake, and the rocks rent; 52And the graves were opened; and many bodies of the saints which slept arose, 53And came out of the graves after his resurrection, and went into the holy city, and appeared unto many. 54Now when the centurion, and they that were with him, watching Jesus, saw the earthquake, and those things that were done, they feared greatly, saying, Truly this was the Son of God.
The New Covenant is GOD's law written on our hearts and minds... The Messiah Gave His Testimony and then suffered much for us..
The saints Keep the Commandments of GOD and Have His Testimony... because He teaches us the Commandments and how to love GOD.
We are made New to worship in Spirit and Truth and our obedient heart is pleasing to Heavenly Father.
The just will live by Faith.
