Jesus said, "...Take heed that NO MAN deceive you." (Matthew 24:4)
Satan is a defeated foe, and trust me, he knows it. His time is running short and he wants to drag as many as he can into eternal hell...
How can you take heed, how can you know if you are being deceived or a false prophet is at work? READ THE WORD OF GOD! STUDY IT! TAKE IT IN! PRAY, PRAY AND PRAY!
Even in the temptation of Christ, when satan so called "quoted" scripture... pay close attention... he twisted it. Satan did NOT speak it completely, he rearranged it to make it mean what he wanted it to. That is why WE as Christians must study the Word of God and seek God through prayer. If we study God's Word, then we will know when the truth is not being given. In these last days, many will come and try to twist it, so study, read and pray so that we can take heed so that no man (or satan) deceives us.
Satan is a imitator, I agree. Satan is also a master deceiver! He is a liar and the father of all lies. That is why in 1 Peter 5:8 the Scriptures warns us to "Be sober, be viligant; because YOUR adversary the devil, as a roaring lion, walketh about, seeking whom he may devour." Be watchful!
I recently preached and gave my testimony at a church a few towns away. I brought out this point...
Have you ever watched on tv a real lion. Such as animal planet or discovery channel. A lion will circle about and watch to pick out the weakest or wounded or youngest of it's prey... it will watch and then pounce to attack.
Satan is referred to in the bible as a lion seeking whom he may devour. Be watchful, study and pray and put on the armour of God, get strength in the Lord... so that you will be strong and make sure you pray and help those that are weak and wounded, so that their strength and faith will build up.
Satan is defeated and he is THE LOSER!!! Stand on God's Word... know that you fight FROM VICTORY NOT FOR VICTORY! JESUS DEFEATED SATAN ON THE CROSS... BUT UNLESS YOU READ AND TAKE IN GOD'S WORD, HOW WILL YOU KNOW.
Remember, "For whatsoever (that You and me) is born of God OVERCOMETH the world: and this is the VICTORY that overcometh, even our FAITH."
Stand on the mighty promises of God.
