When Peter warns believers about a believer's primary adversary in 1 Peter, he gives us some information about who we are up against just in how he describes him. The "devil" is one who falsely accuses and slanders, while "adversary" is literally the word "Satan" in Hebrew. His objective is to DESTROY us, not just to sidetrack us or derail our Christian walk. He does this in three ways: obstruction of the truth, temptation to sin, and oppression meant to drive us from God. While unbelievers will continually fail in resisting these attacks, believers will be overcomers and will never be totally destroyed, since we have assurance that NOTHING can take us out of the love of God.
