Revelation 12:7-12
Satan, being the prince of the power of the air, the spirit that now worketh in the children of disobedience, Ephesians 2:2, has from the time that iniquity was found in him in the garden of Eden, Isaiah 14:12-15; Ezekiel 28:13-15 has always gone to and fro in the earth walking up and down in it, Job 2:2, having access to the throne of God to accuse the brethren while Jesus makes intercession for us before the Father
Satan and his unholy angels are now cast out of heaven forever and cast down to the earth. He is full of wrath as he has no more access to heaven where he stood before the Lord accusing the brethren while Jesus made intercession for them, Romans 8:34. Now is come salvation, strength and the kingdom of our Lord and the power of His Christ as we have overcome Satan by the blood of the Lamb and the word of our testimony as we love not our lives unto death.
Now that Satan has been cast down to earth he is furious as he knows his time is short and he is going to do everything in his own power to silence and destroy the anointed of God as he works through those who have bowed down to him. Salvation brings with its Gods power and authority that gives us the strength to stand against Satan. Strength refreshes us to stand and not be weary, to walk and not give up. We rely on Gods strength to help us through every obstacle that stands in our way. Satan has always tried to fight against us and wear the flesh down, but our strength comes by the indwelling of the Holy Spirit living in us, Isaiah 40:31; Matthew 26:41.
We have been instructed of God to not conform to the world, but to be transformed in the renewing of our mind, Romans 12:2.
Those who have picked up their cross to follow Jesus, Matthew 16:24-28, need not worry that Satan is now out for blood as he will succeed in killing many saints as they die a martyr’s death like those saints before them as they loved not their own life, but have life eternal with the Father. Satan used Emperor Justinian who had around five hundred million Christians killed during his reign and used Paul before his conversion to slaughter the Christians as they both did this in the name of God, 2 Timothy 3:5.
