See 1 Peter 5:8.
Satan brings all kinds of afflictions to the believers (Rev. 2:10).
In Luke 22:31 the Lord Jesus spoke of Satan sifting the believers as grains in a sieve; this is not easy to bear.
In 2 Corinthians 12:7 the apostle Paul speaks of a messenger of Satan buffeting him.
Sometimes Satan accuses the believers before God, sometimes he accuses them in other believers, and sometimes he accuses the believers in themselves. This is indicated in Revelation 12:10.
The apostle Paul said that he had delivered an unrepentant sinner to Satan for the destruction of his flesh. Therefore, sometimes when we are troubled by physical illness, we might have committed a sin that we are unwilling to repent of, thus falling into Satan’s hand to be destroyed by him. This is revealed in 1 Corinthians 5:5 and 1 Timothy 1:20.
See Ephesians 6:11 and 2 Corinthians 2:11.
See 1 Timothy 3:7.
Another work of Satan is to hinder the Lord’s workers. When God’s workers, commissioned by God, go out to work, Satan raises up various environments to hinder them. This is revealed in 1 Thessalonians 2:18.
Demas was a worker of the Lord, but he loved the present age and abandoned Paul (2 Tim. 4:10). This also is Satan’s work.
See Revelation 3:15-17.
See 1 Corinthians 1:11-12 and 3:3-4.
In Christianity there are many doctrines and teachings that are pleasant to the ear but detached from Christ. Although the doctrines and teachings are neither bad nor wrong, they are like winds that toss people back and forth, preventing them from holding Christ, from learning to live in Christ, and from taking Christ as life. This is also a work of Satan that damages the believers.
Teaching in Ephesians 4:14-15 does not refer only to heretical teachings but even to good and correct teachings that cause people to not hold Christ; like the wind, they blow people away from Christ as life. This is a very insidious, damaging work of Satan.
