Satan takes basically four figures or appearances:
First, an angel-of-light figure (2 Corinthians 11:14): This is a wolf in a sheep’s clothing (Matthew 7:15). Since Satan, the Fallen Angel, disguises himself as a sheep, it is very hard to reveal him until it is disclosed by the time set for him. This figure is the most cunning and even treacherous approach made by Satan. He even uses the Word of God, its principles, its teaching, its prayers, its thanksgiving, and so on (used in his own terms).
Second, an innocent-as-a-dove figure: Satan seemingly attacks you indiscriminatorily like we often perceive certain things happened as if they were an accident or life’s crisis (actually it is discriminatory, though). It is his willful act of attack. He enjoys seeing you be suffering. Satan’s treacherous attempts are on purpose for him to see that you are interrupted or obstructed by his attack so that you might challenge God. In this figure, you can see his childish enjoyment in the midst of your destruction or suffering initiated by him. If you are not distracted by his attack, you may disappoint Satan (Hallelujah).
Third, a beast-and-dragon figure: This is a forceful act of Satan. The darkness is his illustration (Acts 26:18). He is a resentful accuser and has often (but not always) a very ugly and frightening appearance like a Halloween depiction. The most of us see Satan in this figure. At worst, he forces to enter into beings (Matthew 8:28-34, the demon-possessed and a herd). In this scenario, things go insane.
Lastly, a temporarily-invasive figure: This may happen even to a man of God. For example, Jesus asked his disciples the following question,“Who do you say I am?” (Mathew 16:13-15 NIV). Peter answered, “You are the Messiah, the Son of the Living God” (Matthew 16:16 NIV). Jesus replied, “Blessed are you, Simon son of Jonah, for this was not revealed to you by flesh and blood, but by the Father in heaven” (Matthew 16:17 NIV). And then Jesus began to explain to his disciples his death. Peter reacted to Jesus like this, “Peter took him aside and began to rebuke him, ‘Never, Lord!’ he said. ‘This shall never happen to you!'” (Matthew 16:21-22 NIV). Jesus responded immediately to Peter in the following manner, “Jesus turned and said to Peter, ‘Get behind me, Satan! You are a stumbling block to me; you do not have in mind the concerns of God, but merely human concerns'” (Matthew 16:23 NIV).
While attacking, Satan cannot see the end results of each attack because he lost his spiritual insight and ability to foresee the outcome since he became the Adversary. He merely hates and opposes bitterly all directions the Lord intends. He knows his own fate and destiny resulted by the consequence of his rebellion against God and by his knowledge of the Bible verses (Genesis, Revelation, etc.) which deal particularly with himself but it doesn’t change him anyway because of the evil at the core of Satan (the core of Satan by nature is evil).
We read Ephesians 6: 12 NKJV, “For we do not wrestle against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this age, against spiritual hosts of wickedness in the heavenly places.” – T
