What does the Bible say about the devil's influence on believers?

The Scriptures identify the devil as a fierce adversary to Christians, eager to bring about their destruction. In Luke 22:31, Jesus warns Peter that Satan desires to sift him like wheat, highlighting the subtlety and malevolence of this enemy. Throughout Scripture, the devil is depicted as a liar, a murderer, and a constant accuser (John 8:44, 1 Peter 5:8). Believers must recognize this influence and remain vigilant in their spiritual lives, for the devil seeks to exploit human weaknesses and sow doubt and division within the church.
