How is the “son of man’s” kingdom different? It is created out of honour, not bloodshed. And it is eternal.
Note The “little horn” may represent Antiochus Epiphanes, who reigned from 175 to 164 B.C.E., king of the former Persian empire. He tried ot abolish the traditional jewish religion, see pp.105-109.
I think everyone has access to “the kingdom of God” & it’s up to us to choose. If we spend time in prayer & quiet time with God / ourselves – I think our heart/ God tells us / we hear & know the right path – but to find this path we need to have prayer time & make time to find our route forward. I guess like any “route / map planning” you need to spend time – & that for Gods path & access into God’s kingdom is through prayer . It’s not easy but it’s possible for everyone – regular prayer & making enough time for it helps me .
