Got it pad old chum! Get yerself a glass of red eye and sit down.
Who says that a person who serves at the altar is saved? Not only that but the Lord promises to make their lives right miserable to boot!
Right between the eyes.
The children suffering the sins of the father!
The Lord declares that dead men 'will' serve Him at His altar. But only to crush them.
He does as He pleases.
Ciaphas said that it would be a jolly good idea for one man to die for the nation rather than the nation perish. The end of the line?
1 Samuel 3:14 “Therefore I have sworn to the house of Eli that the iniquity of Eli’s house shall not be atoned for by sacrifice or offering forever.”
That stands.
Problem resolved?
1 Samuel 2:33 ‘Yet I will not cut off every man of 'yours' from My altar so that your eyes will fail from weeping and your soul grieve, and all the increase of your house will die in the prime of life.
What is that translation?
KJV.
1 Sam 2:33 And the man of thine, whom I shall not cut off from mine altar, shall be to consume thine eyes, and to grieve thine heart: and all the increase of thine house shall die in the flower of their age.
NIV.
1 Sam 2:33 Every one of you that I do not cut off from my altar will be spared only to blind your eyes with tears and to grieve your heart, and all your descendants will die in the prime of life.
Some more. The NIV reads different to the other two. The NIV reads better because I think it does.

'Every one of you...your eyes will not see for tears.'
He is giving Eli's house knowledge of their doom in advance. Dead men walking. They knew that! They could do nothing about it. In the same way He has told me that the life I have will only ever get better. And I can do nothing about that.
That does for the argument that Jesus died and atoned for all sin. It leaves a whacking great hole in someones edifice!
Surrender terms are available. They are surrender. Unconditional surrender I think!
