A person living in the world of sin is not the devils target, active Christians are. Think about it; why would Satan go after people in the world? He already has them just where he wants them. Today he isn’t fighting the church, he’s joining it. One of his main targets now is destroying the family units, causing marital strife but he is also causing strife in many other areas of life for humans whether they are in or out of the church. Today he is wrecking havoc any and everywhere. Beware and on guard. He does more harm by sowing tares than by pulling up wheat. We must remember that Satan is also a fisher of men and not only does he cast his net in the world but he is casting it in the church as well. Satan himself masquerades as an angel of light. His servants also disguise themselves as servants of righteousness. 2 Corinthians 11:14-15. "Satan's greatest weapon is man's ignorance of God's Word." Satan knows the difference between a professing Christian and a True Believer.
The Bible does tell us that for the believer nothing happens outside God's control—and yes, if we know Christ, His angels continually watch over us. The Bible says that God "will command his angels concerning you to guard you in all your ways" (Psalm 91:11). It also teaches that the angels—although they are largely unseen—watch over us and work for our good. The Bible says, "Are not all angels ministering spirits sent to serve those who will inherit salvation?" (Hebrews 1:14).
Rather than only one angel, therefore, God surrounds us with a host of angels to protect us and go before us. Even when hard times come, Satan can never snatch us away from their protection—and some day they will escort us safely to heaven. The reality of God's angels should give us great confidence in the Bible's promises. Whenever you deal with temptation, you realize Satan is smooth and shrewd. He makes disobeying God and doing the wrong thing seem logical, even attractive–not to mention wise, clever and sophisticated. That last one gets to a lot of people. You have people today who cannot discern God's voice from Satan's voice. 2nd Corinthians 11: 13-15. For such men are false apostles, deceitful workers, disguising themselves as apostles of Christ. No wonder, for even Satan disguises himself as an angel of light. Therefore it is not surprising if his servants also disguise themselves as servants of righteousness, whose end will be according to their deeds.
Great is the power of Satan, and strong is the hold he has upon us by reason of the evil that is in us. We cannot escape his cruel and dangerous assaults. But we have a precious ally and intercessor in Jesus Christ. His heart and tender sympathy go with us in our trials. God will never leave us wanting, He will fulfill every need. There is NOTHING Satan can do for us.
