Biblical explanation
Satan is called: The Devil: Matthew 4:1 Satan: Revelation 12:9 The tempter: Matthew 4:3 The adversary: 1 Peter 5:8 The accuser: Revelation 12:10 The deceiver: Revelation 12:9 A murderer and liar: John 8:44 The god of this world: 2 Corinthians 4:4 Peter warns believers to remain vigilant: "Be sober, be vigilant; because your adversary the devil... walketh about, seeking whom he may devour." 1 Peter 5:8, KJV Paul says believers are not ignorant of Satan's devices (2 Corinthians 2:11). Yet Satan is not God's equal. He is a created being under God's ultimate authority. The Bible gives Satan significant power, but never presents him as omnipotent, omniscient, or omnipresent. He is powerful, but he is still a creature. His final defeat is certain.
Key takeaway
Discipleship applies the gospel to the whole life: body, mind, relationships, work, finances, and worship. Healthy choices and faithful habits do not earn salvation; they are grateful stewardship of the life God has entrusted to us and practical ways to serve others.
