Our society does not regard Satan as a real being. Even in some churches the members will ignore this. But Scripture tells us otherwise. There is a real evil being and he does a lot of under cover work in the area of mental illness, divorce, physical & sexual abuse, self degrading, insecurities and so on.
When we read Mark 5:1-5 we see that Satan likes to isolate, shame and torture the people he controls. His power is inhumanely strong and he uses this to hold people in fear and bondage. When the evil one achieves a hold in our lives he will lead us into self-destructive behaviour.
Satan is around and he is roaming and wanting to destroy as many lives as he can before the return of our Lord Jesus Christ. As his time grows short, he is becoming fiercer and if he notices that he can have a chance with you in pulling you away from Jesus or stop you doing the work God has for you, he will. He will tempt and deceive you. He is a seducer and will stop at no means to take you down.
Focus your thoughts on Jesus Christ and His word. He will fill you up and defeat the tactics of Satan. When Jesus brings to mind a sin you have done, just repent of it and ask for His forgiveness, this closes up the hole that Satan can get a foothold on, Ephesians 4:26-27. Get involved in a church and have people praying for you. Remember Satan wants to isolate you and bring you into darkness. Where there is light the darkness must flee. And when you see someone under distress, pray for them. Have compassion on them and realize that this is a spiritual war and they are under attack and are in need of prayer and maybe need leading into repentance for a sin they have committed, like anger, hatred or just pure frustration.
1 John 1:5-7 NIV
This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth. But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
Praise Jesus, He has overcome the darkness and through Him we can too.
