It's actually scriptural.
John: 9. 31. Now we know that God heareth not sinners: but if any man be a worshipper of God, and doeth his will, him he heareth. 32. Since the world began was it not heard that any man opened the eyes of one that was born blind. 33. If this man were not of God, he could do nothing. 34. They answered and said unto him, Thou wast altogether born in sins, and dost thou teach us? And they cast him out. 35. Jesus heard that they had cast him out; and when he had found him, he said unto him, Dost thou believe on the Son of God? 36. He answered and said, Who is he, Lord, that I might believe on him? 37. And Jesus said unto him, Thou hast both seen him, and it is he that talketh with thee. 38. And he said, Lord, I believe. And he worshipped him. 39. And Jesus said, For judgment I am come into this world, that they which see not might see; and that they which see might be made blind. 40. And some of the Pharisees which were with him heard these words, and said unto him, Are we blind also? 41. Jesus said unto them, If ye were blind, ye should have no sin: but now ye say, We see; therefore your sin remaineth.
Hebrews: 10. 17. And their sins and iniquities will I remember no more. 18. Now where remission of these is, there is no more offering for sin. 19. Having therefore, brethren, boldness to enter into the holiest by the blood of Jesus, 20. By a new and living way, which he hath consecrated for us, through the veil, that is to say, his flesh; 21. And having an high priest over the house of God; 22. Let us draw near with a true heart in full assurance of faith, having our hearts sprinkled from an evil conscience, and our bodies washed with pure water. 23. Let us hold fast the profession of our faith without wavering; (for he is faithful that promised

24. And let us consider one another to provoke unto love and to good works: 25. Not forsaking the assembling of ourselves together, as the manner of some is; but exhorting one another: and so much the more, as ye see the day approaching. 26. For if we sin wilfully after that we have received the knowledge of the truth, there remaineth no more sacrifice for sins, 27. But a certain fearful looking for of judgment and fiery indignation, which shall devour the adversaries. 28. He that despised Moses' law died without mercy under two or three witnesses: 29. Of how much sorer punishment, suppose ye, shall he be thought worthy, who hath trodden under foot the Son of God, and hath counted the blood of the covenant, wherewith he was sanctified, an unholy thing, and hath done despite unto the Spirit of grace? 38. Now the just shall live by faith: but if any man draw back, my soul shall have no pleasure in him. 39. But we are not of them who draw back unto perdition; but of them that believe to the saving of the soul.
I could literally use any section of the Bible you would like to show the truth that was given to us.
You are wrong if you thing GOD will accept the knowing sinner into HIS abode.
