I believe you have missed the point;
We are not part of God's kingdom until after death and His judgement to be so. We have no authority to put ourselves in the presence of God until judged to do so with the award of eternal salvation. That can only occur after our physical death.
Until then we are ...born again...not saved.
That's OK, for we are sanctified by His Blood poured out for us on the Mercy Seat which HE took to the throne of God on our behalf.
We see the Effectual Act of Justification of this in Scripture: Matt ch27
And Jesus cried out again with a loud voice, and yielded up His spirit.
51Then, behold, the veil of the temple was torn in two from top to bottom; and the earth quaked, and the rocks were split,
52and the graves were opened; and many bodies of the saints who had fallen asleep were raised;
53and coming out of the graves after His resurrection, they went into the holy city and appeared to many.
54So when the centurion and those with him, who were guarding Jesus, saw the earthquake and the things that had happened, they feared greatly, saying, “Truly this was the Son of God!”
