He is the murderer – He wants to destroy Jn. 8:44  Ye are of your father the devil, and the lusts of your father ye will do. He was a murderer from the beginning, and abode not in the truth, because there is no truth in him. When he speaketh a lie, he speaketh of his own: for he is a liar, and the father of it.

He is the roaring lion – frightening, fierce, causing fear & dread 1 Pet. 5:8  Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:

The prince of this world Eph. 2:2 2 in which you once walked according to the course of this world, according to the prince of the power of the air, the spirit who now works in the sons of disobedience,
He has power in the earthly realm until the final overthrow at the second coming of Christ and the judgment He has limited power to fight against Christ and His church
Ultimately he will fail 1 Jn. 5:4  For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith.
1. Satan, our enemy, is very clever 2 Cor. 11:13-14  For such are false apostles, deceitful workers, transforming themselves into the apostles of Christ.  And no marvel; for Satan himself is transformed into an angel of light.
2 Cor. 11:3 – he is beguiling (misleading, full of tricks) 3 But I fear, lest somehow, as the serpent deceived (beguiled) Eve by his craftiness, so your minds may be corrupted from the simplicity[a] that is in Christ.
1 Jn. 5:19 – he is very deceptive  And we know that we are of God, and the whole world lieth in wickedness.
2. The devil is strong Satan’s power has been limited by Christ’s death and resurrection– but he is still a powerful enemy He opposes God’s people and the work they do We must depend upon God for strength

3. This great enemy can be overcome Eph. 6:10-18  Finally, my brethren, be strong in the Lord, and in the power of his might. Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
 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.
 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness; And your feet shod with the preparation of the gospel of peace;
 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked. And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
We must be obedient to Christ and build a spiritual relationship with Him
1 Jn. 3:8 - Christ came to destroy the works of the devil  He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
