Are you familiar with a business that is 24/7 open? or A 24/7 customer service support? The best example is a Call Center business that is open twenty four hours a day seven days a week.
The 24 hour service offered might be true but the person working in day time is not the same person working at night for surely they have shifting schedules.
But do you know that there is one in the Bible who worketh, accusing us before God, day and night 24/7 without replacement?
Revelation 12:10 And I heard a loud voice saying in heaven, Now is come salvation, and strength, and the kingdom of our God, and the power of his Christ: for the accuser of our brethren is cast down, which accused them before our God day and night.
Genesis 2:2 And on the seventh day God ended his work which he had made; and he rested on the seventh day from all his work which he had made.
The verses below prove how active Satan is. He is always present even without invitation. In spanish parlance, he is "presentado alsado".
Job 2:1 Again there was a day when the sons of God came to present themselves before the LORD, and Satan came also among them to present himself before the LORD.
Job 2:2 And the LORD said unto Satan, From whence comest thou? And Satan answered the LORD, and said, From going to and fro in the earth, and from walking up and down in it.
1 Peter 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
Is the activity of Satan from going to and fro or walking up and down on earth permitted by God?
Revelation 22:11 He that is unjust, let him be unjust still: and he which is filthy, let him be filthy still: and he that is righteous, let him be righteous still: and he that is holy, let him be holy still.
Genesis 15:16 But in the fourth generation they shall come hither again: for the iniquity of the Amorites is not yet full.
2 Peter 3:9 The Lord is not slow in keeping his promise, as some understand slowness. He is patient with you, not wanting anyone to perish, but everyone to come to repentance.
