Unless one is blameless under that law, and has no knowledge of justification through Jesus.
No one is blameless, even in the OT, everyone was justified by faith, and not works of the law.
What you're actually saying is anti-Christ, in that people can be going to the Father without the ministry of Christ who is our great high priest to God. There are no exceptions, for all have sinned. Not believing in Christ is a sin and it will kill you, as Christ says those who do not believe in Him, die in their sins. And are condemned with the wrath of God abiding on them
NT, John 3
35 The Father loves the Son, and has given all things into His hand. 36 He who believes in the Son has everlasting life; and he who does not believe the Son shall not see life, but the wrath of God abides on him.”
OT, Habakkuk 2:4
“Behold the proud, His soul is not upright in him; But the just shall live by his faith.
If people could go and live with God in heaven without Christ, that makes His death on the cross unnecessary, and so then all of Christianity is not important.
But God says this again in Acts 17 about the judgement, he commands all men everywhere to repent, as He will judge them by Christ alone, and Christ says no one comes to the Father but by Him, Christ is the door of the sheep to enter into God's kingdom.
Look at each verse here and see for yourself.
John 10
New King James Version
Jesus the True Shepherd
1 “Most assuredly, I say to you, he who does not enter the sheepfold by the door, but climbs up some other way, the same is a thief and a robber.
2 But he who enters by the door is the shepherd of the sheep. 3 To him the doorkeeper opens, and the sheep hear his voice; and he calls his own sheep by name and leads them out.
4 And when he brings out his own sheep, he goes before them; and the sheep follow him, for they know his voice. 5 Yet they will by no means follow a stranger, but will flee from him, for they do not know the voice of strangers.” 6 Jesus used this illustration, but they did not understand the things which He spoke to them.
7 Then Jesus said to them again, “Most assuredly, I say to you, I am the door of the sheep. 8 All who ever came before Me are thieves and robbers, but the sheep did not hear them.
Acts 17
Therefore, the One whom you worship without knowing, Him I proclaim to you: 24 God, who made the world and everything in it, since He is Lord of heaven and earth, does not dwell in temples made with hands. 25 Nor is He worshiped with men’s hands, as though He needed anything, since He gives to all life, breath, and all things. 26 And He has made from one [j]blood every nation of men to dwell on all the face of the earth, and has determined their preappointed times and the boundaries of their dwellings, 27 so that they should seek the Lord, in the hope that they might grope for Him and find Him, though He is not far from each one of us; 28 for in Him we live and move and have our being, as also some of your own poets have said, ‘For we are also His offspring.’ 29 Therefore, since we are the offspring of God, we ought not to think that the Divine Nature is like gold or silver or stone, something shaped by art and man’s devising. 30 Truly, these times of ignorance God overlooked,
but now commands all men everywhere to repent, 31 because He has appointed a day on which He will judge the world in righteousness by the Man whom He has ordained. He has given assurance of this to all by raising Him from the dead.”
32 And when they heard of the resurrection of the dead, some mocked, while others said, “We will hear you again on this matter.” 33 So Paul departed from among them. 34 However, some men joined him and believed, among them Dionysius the Areopagite, a woman named Damaris, and others with them.
