We know that anyone born of God does not continue to sin; the One who was born of God keeps them safe, and the evil one cannot harm them. We know that we are children of God, and that the whole world is under the control of the evil one. We know also that the Son of God has come and has given us understanding, so that we may know him who is true. And we are in him who is true by being in his Son Jesus Christ. He is the true God and eternal life.
-1 John 5:18-20

Christians commit sin, of course, but they ask God to forgive them, and then they continue serving him. God has freed believers from their slavery to Satan, and he keeps them safe from Satan's continued attacks. The rest of the world does not have the Christian's freedom to obey God. Unless they come to Christ in faith, they have no choice but to obey Satan. There is no middle ground — people either belong to God and obey him, or they live under Satan's control.
