“Why do you not understand My speech? Because you are not able to listen to My word.  You are of your father the devil, and the desires of your father you want to do. He was a murderer from the beginning, and does not stand in the truth, because there is no truth in him. When he speaks a lie, he speaks from his own resources, for he is a liar and the father of it.  But because I tell the truth, you do not believe Me.  Which of you convicts Me of sin? And if I tell the truth, why do you not believe Me?  He who is of God hears God’s words; therefore you do not hear, because you are not of God.”(John 8:43‭-‬47)

John 10:10 says,the only reason a thief comes ,is to steal, kill, and destroy. And

2Corinthians 2:11 warns us, be alert,Lest Satan should get an advantage of us: for we are not ignorant of his devices. 

The thief is satan the devil himself. Where there is stealing, killing and destruction the devil is at work. In every evil act that takes place,the devil is at work. He influences and operates through mankind since the Garden of Eden with Eve and Adam. The unfortunate thing is that many do not see it that way. They see mankind as evil instead of the devil. This is exactly what the devil wants. This is deception. Be not deceived. Open Your eyes; the devil is your enemy and not mankind,and Jesus already defeated him,therefore, Blessed you are and blessed you will always be and to God be all the glory. Amen!
