Many would say that Satan is not always involved with our sin; that Satan, the world, and our flesh stand on their own and we should deal with them separately. But the bible seems to indicate otherwise. I would suggest that the world, the flesh, and the devil are all connected.
While I was reading Ephesians 6:12 last night, it was made clear to me that all our spiritual struggles (to sin) are ultimately against the devil and his demons.
For our struggle is not against flesh and blood, but against the rulers, against the powers, against the world forces of this darkness, against the spiritual forces of wickedness in the heavenly places.
We don’t very often recognize this fact, because it seems to us that our sin comes from inside us—from our fleshly nature. And this is true! However, just because we still have this flesh doesn’t mean we have to sin. In fact, I don’t think our flesh would have much power over us at all if it wasn’t for the devil and the world. The book of 1 John helps us understand this—to understand the connections.
I John 2:16 shows us the connection of our sinful flesh to the world.
For all that is in the world, the lust of the flesh and the lust of the eyes and the boastful pride of life, is not from the Father, but is from the world.
All the things of the world indeed compel us to sin. That is, the things in the world (examples: new houses, new cars, new clothes, vacations, lustful relationships, pleasures, all forms of pornography) creates sinful desires in us, desires that are called in the bible, “works of darkness” (Eph. 5:11). (This term “darkness” denotes the kingdom of Satan).
Indeed, the world would have no power against us if it wasn’t for Satan and his demons. For I John 5:19b says,
…the whole world lies in the power of the evil one.
Therefore, Satan controls the world as his puppet—with the purpose of deceiving us, tempting us to sin, and ultimately keeping us from God and His grace.
In the end of days, during the millennium (when Satan is locked up), though there will be many on the earth who are not believers, I don’t think their sin will have much power. Indeed, I think their chief sin is that they will not believe. But when Satan is released from his prison, that is when all the unbelievers will find a new power to sin; for Satan will once again, in a short time, take power over the world, and by his deception will move all the unbelievers to rebel against God and Christ.
