of course, under 神的主權, all things happens.

亞當夏娃used their free will 墮落,under 神的主權,
人, has no other choices but 犯罪,under 神的主權,
some of sinners are redeemed under/by 神的主權,

are you familiar with the concept of ONE way?
fluid can be flowing one way not reversely,
light shines out not reversely,
life from birth till death not possible to be incarnating
......

人, can 犯罪under/by 神的主權, but never possible
to find GOD under/by 神的主權 ,
人, can use his/her own will do a lot things including good things
under 神的主權
