I don't believe you've made a good case for that.
Either way, my personal spiritual condition is not what the question is based on.
Do you believe a person can be someone that you would consider a devout, serious Christian for many years and still be ignorant of God's desires concerning the seventh day?
So you don't accept Paul's statement that we are mortal and must put on immortality when we are changed at the 2nd coming. And since the Bible says when a man dies his thoughts perish how can anyone be looking down from heaven?
Job 14: 8 Though the root thereof wax old in the earth, and the stock thereof die in the ground;
9 Yet through the scent of water it will bud, and bring forth boughs like a plant.
10
But man dieth, and wasteth away: yea, man giveth up the ghost, and where is he?
11 As the waters fail from the sea, and the flood decayeth and drieth up:
12
So man lieth down, and riseth not: till the heavens be no more, they shall not awake, nor be raised out of their sleep.
How about Jesus' words?
Luke 11: 1 NOW a certain man was sick, named Lazarus, of Bethany, the town of Mary and her sister Martha.
2 (It was that Mary which anointed the Lord with ointment, and wiped his feet with her hair, whose brother Lazarus was sick.)
3 Therefore his sisters sent unto him, saying, Lord, behold, he whom thou lovest is sick.
4 When Jesus heard that, he said, This sickness is not unto death, but for the glory of God, that the Son of God might be glorified thereby.
5 Now Jesus loved Martha, and her sister, and Lazarus.
6 When he had heard therefore that he was sick, he abode two days still in the same place where he was.
7 Then after that saith he to his disciples, Let us go into Judæa again.
8 His disciples say unto him, Master, the Jews of late sought to stone thee; and goest thou thither again?
9 Jesus answered, Are there not twelve hours in the day? If any man walk in the day, he stumbleth not, because he seeth the light of this world.
10 But if a man walk in the night, he stumbleth, because there is no light in him.
11
These things said he: and after that he saith unto them, Our friend Lazarus sleepeth; but I go, that I may awake him out of sleep.
12 Then said his disciples, Lord, if he sleep, he shall do well.
13
Howbeit Jesus spake of his death: but they thought that he had spoken of taking of rest in sleep.
14
Then said Jesus unto them plainly, Lazarus is dead.
15 And I am glad for your sakes that I was not there, to the intent ye may believe; nevertheless let us go unto him.
According to Jesus Lazarus was dead yet He referred to his death as sleep. If anyone knows the state of a dead person it is God.
John 20: 15 Jesus saith unto her, Woman, why weepest thou? whom seekest thou? She, supposing him to be the gardener, saith unto him, Sir, if thou have borne him hence, tell me where thou hast laid him, and I will take him away.
16 Jesus saith unto her, Mary. She turned herself, and saith unto him, Rabboni; which is to say, Master.
17
Jesus saith unto her, Touch me not; for I am not yet ascended to my Father: but go to my brethren, and say unto them, I ascend unto my Father, and your Father; and to my God, and your God.
Jesus died Friday afternoon and had not yet been to heaven by Sunday morning.
