It is obvious today Christians can't count 70 generations let alone 1000:
Deu 7:9 Know therefore that YaHUaH thy God, he is God, the faithful God, which keepeth covenant and mercy with them that love him and keep his commandments to a thousand generations
No mercy for those that don't love Him (Messiah) enough to keep His commandments for the next 70,000 years:
your disobedience = no covenant, no mercy, no tree of life
Rev 22:14 Blessed are they that do his commandments, that they may have right to the tree of life, and may enter in through the gates into the city.
