Is it true that Satan must ask God's permission for every single little thing and temptation he desires to foist upon God's children and creation writ large? Or does God give him a certain latitude that he may creatively unleash hell on us, but only to a certain point, like a dog with a shock collar going to far off the property and getting zapped because he went to far? We see in Job that Satan asked permission but does this story apply to everyone else today?
Satan has God's permission to tempt (satan tempted Jesus) ... and we often fall for the temptation(s) ... we don't have to fall for the temptation.
Such was the case with Job. The temptation(s) included disastrous events with Job .... even so .... He remained faithful to God ... Job did not yield to the temptations of satan and remained faithful to God.
James 1
13When tempted, no one should say, “God is tempting me.” For God cannot be tempted by evil, nor does He tempt anyone.
14But each one is tempted when by his own evil desires he is lured away and enticed.
15Then after desire has conceived, it gives birth to sin; and sin, when it is full-grown, gives birth to death.
1 Corinthians 10:13
No temptation has overtaken you that is not common to man. God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it.
James 4:7
Submit yourselves therefore to God. Resist the devil, and he will flee from you.
