“For I am convinced that neither death nor life, neither angels nor demons, neither the present nor the future, nor any powers, neither height nor depth, nor anything else in all creation, will be able to separate us from the love of God that is in Christ Jesus our Lord.” -Romans 8:38-39
The persecution facing Christians in Rome at Paul’s time was strong. Much like that faced by Christians persecuted by Daesh death cult. It is said Nero used Christians as human torches to light his gardens. Paul faced that persecution, and died. But before he died, he provided this powerful testimony. There is no promise of lust or money, no threat of pain or destruction, no loss, which will prevent God from holding us as we call and serve Him.
On his Journey to Rome, Paul was stoned, probably to death. But Paul persevered.
We are challenged by Demons. But it is not our job to fight those demons. We should resist them. If we fight demons, we end up dancing to the tune they play. But God will fight them and win. It has been written in Revelations that He will throw them into a black pit. All you need do, is hold onto God.
