God brought them back to their nationhood after 2000 years. At that point it definitely applies:”I will bless those who bless you,
And I will curse him who curses you;” Gen 12
Isaiah 55:7 ESV
Let the wicked forsake his way,
and the unrighteous man his thoughts;
let him return to the Lord,
that he may have compassion on him,
and to our God, for he will abundantly pardon.
Ezekiel 33:11 ESV
Say to them, As I live, declares the Lord God,
I have no pleasure in the death of the wicked,
but that the wicked turn from his way and live;
turn back, turn back from your evil ways,
for why will you die, O house of Israel?
Proverbs 28:13 ESV
Whoever conceals his transgressions will not prosper,
but he who confesses and forsakes them will obtain mercy.
