We can agree that Satan is only one person and not omnipresent in his own person. But his influence can be felt by everyone in the world at any or all times. He can send his angels out to bother every one of us. This is the reason to cast Satan out of your life in the name of Jesus Christ. I do this anytime I do not feel the presence of God when I try to talk to Him.
" 'I am Jesus, whom you are persecuting,' the Lord replied. 16'Now get up and stand on your feet. I have appeared to you to appoint you as a servant and as a witness of what you have seen of me and what I will show you. 17I will rescue you from your own people and from the Gentiles. I am sending you to them 18to open their eyes and turn them from darkness to light, and from the power of Satan to God, so that they may receive forgiveness of sins and a place among those who are sanctified by faith in me.' Acts 26:16-18

wonders,
