what does the bible say?
Scripture does not teach that people can “sell” their souls to the Devil. However, Satan is the “ruler” and “god” of this world (John 12:31; 14:30; 2 Corinthians 4:4). He holds power (1 John 5:19) to influence both unbelievers and believers with his deceit and false doctrines (1 Timothy 4:1; Acts 16:16-19) as well as scheme and carry out spiritual attacks (1 Peter 5:8-9). We can resist Satan’s deceit by hiding God’s Word in our heart (Psalm 119:11) and putting on the full armor of God (Ephesians 6:11). When we use God’s Word as our weapon, Satan will have no choice but to flee from us (James 4:7). We must be especially on guard against false teachings in the church, as it is all too easy to tolerate or even follow those who directly contradict the teachings of the Bible like some did in the church of Thyatira in Revelation 2:20. Taking all this into account, we can find peace knowing our souls cannot be sold to Satan—and no temptation can overtake us, either (1 Corinthians 10:13).
