1 Peter 5:8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour: 9 Whom resist stedfast in the faith, knowing that the same afflictions are accomplished in your brethren that are in the world. 10 But the God of all grace, who hath called us unto his eternal glory by Christ Jesus, after that ye have suffered a while, make you perfect, stablish, strengthen, settle you. 11 To him be glory and dominion for ever and ever. Amen.
You are learning who the enemy is as it is not people, but Satan working through others as he wants to destroy you by stealing your faith in Christ. You are an overcomer as Jesus already fought that battle over the evil dominion over this world and has given us the victory over the principalities of darkness in this world.
Ephesians 6:10 Finally, my brethren, be strong in the Lord, and in the power of his might. 11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil. 12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
Satan is a liar and he really can just go back to Hell where he belongs!!!
