In order to defeat or win against Satan and to honor our God, we must be able to distinguish the two clearly.  This article is a bible study which compares God and Satan from a Biblical perspective.  We are the sheep and our God is the good Shepherd.  If we are to avoid harm, we must recognize our shepherd and follow Him, but avoid Satan, who is a stranger, a thief, and a destroyer.  To God, he is a "sheep poacher".  The parable of the Good Shepherd tells this story clearly in John 10:1-11:

"Most assuredly, I say to you, he who does not enter the sheepfold by the door, but climbs up some other way, the same is a thief and a robber.  But he who enters by the door is the shepherd of the sheep.  To him the doorkeeper opens, and the sheep hear his voice; and he calls his own sheep by name and leads them out.  And when he brings out his own sheep he goes before them; and the sheep follow him, for they know his voice."  Jesus used this illustration, but they did not understand the things which He spoke to them.

Then Jesus said to them again, "Most assuredly, I say to you, I am the door of the sheep.  All who enter came before Me are thieves and robbers, but the sheep did not hear them.  I am the door.  If anyone enters by Me he will be saved, and will go in and out and find pasture.  The thief does not come except to steal, and kill, and to destroy.  I have come that they may have life, and that they may have it more abundantly.  I am the good shepherd.  The good shepherd gives His life for the sheep."

If Jesus came today, would you as His sheep know His voice and recognize Him as your Shepherd?  Would you be able to distinguish Him from the Antichrist?  1 John 2:18 and 2 John 1:7 warn us that there will be many false prophets and antichrists.  Have you studied God's word and put on the Armor of God (Eph 6:11-17) so that you will be able to discern these false prophets and teachers and recognize your Shepherd?  The table below will hopefully help you with that process of discernment and judgment.  If you as a Christian are unwilling or unable to exercise that level of judgment because you have been taught a false standard of not judging, then may God help your soul because there is no hope for you where you are going:

"The lips of the righteous nourish many, but fools die for lack of judgment." 
[Prov. 10:21, Bible, NKJV]

"Judge not according to appearance, but judge righteous judgment." 
[Jesus speaking in John 7:24]
