May you have peace!
Your mother might benefit from reading the following, which the WTBTS has overlooked since its inception:
"Now, through Christ we have THIS sort of confidence toward God. Not that we of ourselves are adequately qualified to reckon anything as issuing from ourselves, but our being adequately qualified issued from God, who has indeed adequately qualified us to be ministers of a NEW covenant, NOT of a written code, but of SPIRIT; for the written code condemned to death, but the SPIRIT makes alive.
"Moreover, if the code which administers death and which was engraved with letters in stones came about in a glory, so that the sons of Israel could not gaze intently at the face of Moses because of the glory of his face, a glory that was to be done away with, why should not the administering of the SPIRIT be much more with glory? For if the code administering condemnation was glorious, MUCH more does the administering of righteousness abound with glory. In fact, even that which has once been made glorious HAS BEEN STRIPPED OF GLORY in this respect, because of the glory that EXCELS it. For if that which was to be done away with was brought in with glory, MUCH more would that which REMAINS be with glory.
"Therefore, as WE have such a hope, WE are using GREAT freeness of speech, and NOT doing as when Moses would put a veil upon his face, that the sons of Israel might NOT gaze intently at the end of that which was to be done away with. But THEIR mental powers were DULLED. For to this present day the SAME veil remains... UNLIFTED... at the reading of the Old Covenant, because IT IS DONE AWAY WITH... by means of CHRIST. In fact, DOWN TILL TODAY... WHENEVER MOSES IS READ... A VEIL LIES... UPON THEIR HEARTS. BUT... when there is a turning to the CHRIST (please see NWT Ref. Bible footnote!! Do NOT rely on the abridged version!)... the veil... IS TAKEN AWAY. Now, the Christ... IS THE SPIRIT, and where the Spirit of the Christ is... THERE IS FREEDOM.And all of US, while WE... with UNVEILED faces... reflect like mirrors... the glory of the CHRIST... are TRANSFORMED... INTO THE SAME IMAGE... from glory... TO glory... EXACTLY as done... by Christ... the Spirit.
2 Corinthians 3:4-18
The emphasis that I have included is not mine; it is that which I received from the Spirit, Christ. I did not know of its existence in Paul's letter (which, by the way, is not inspired) until my Lord showed it to me... and read it to me just as I have emphasized it here. It was then that I understood the replacement of the Old Covenant... with the NEW covenant... and what happens to our HEARTS when we try to adhere... and have others adhere... to the Old: not only is doing so a direct denial of blessings of the Spirit, Christ, but WE BLOCK OUT GOD!
That is because the OLD Law... stands BETWEEN us... and God. If we REMOVE that Law, however, from our HEARTS... and replace it with CHRIST... only THEN we are granted to see the "glory" of God that IS the Christ. This is because we REFLECT that glory, Christ, in our OWN hearts and lives.
I bid you the greatest of love and peace.
Your servant and a slave of Christ,
