Lub advent ntawm Kev lag luam Nws ua rau qhov teeb meem no hloov pauv ntau, ua rau muaj kev sib pauv ntawm cov khoom lag luam ntawm txawv teb chaws, uas tau tsim lub hauv paus rau dab tsi niaj hnub no peb xav tias yog qee yam zoo ib yam, uas yog kev lag luam thoob ntiaj teb.

Yog li, ib qho xwm txheej hauv ntiaj teb tau tsim nyob rau hauv uas cov tebchaws uas tau thov cov khoom siv raw tau mob siab rau lawv rho tawm, thaum lub tebchaws uas tsis muaj cov khoom siv raw no, tab sis muaj cov ntsiab lus siab tshuab rau hloov nws muaj txiaj ntsig, lawv yuav lawv thiab hloov pauv mus rau hauv cov khoom tiav, uas tau muab rau tom khw raws li cov khoom tiav.

Txawm hais tias qhov txheej txheem thoob ntiaj teb ntawm kev tsim khoom tau hloov pauv nrog lub sijhawm thiab kev nom kev tswv, lub hauv paus tseem tsis tau hloov pauv, tej zaum nws tau hais lus ntau dua nrog cov txheej txheem ntawm ntiaj teb no.
