I think Satan is served when people believe anything other than God.
Jesus said, "I am the way, the truth, and the life; no one comes to the Father except by me."
In short, there is no problem with Truth. Faith in God says that God's way will be perfectly aligned with Truth.
Folks simply need to slide right into God's salvation that He's purchased for them through the sacrifice of His Son. If they resist they continue in their lost state.
From that perspective of faith, those who are sincere in their faith in Christ can rest in the knowledge that God's in control of everything....including origins and endings.
Those who do bad in the name of God are the best tools of Satan.
