1 John 5:18 We know that whosoever is born of God sinneth not; but he that is begotten of God keepeth himself, and that wicked one toucheth him not.
19 And we know that we are of God, and the whole world lieth in wickedness.
John in these verses tells us if we are born of God we should be free of sin. We have to make a conscience effort to not give in to sin even after we are saved. Satan does not worry about those that are lost, he already has them, but he has to focus his attention on the believer to try to turn them. If we are true children of God we should be increasing our knowledge everyday of Him so we can defeat Satan every day. God’s only begotten Son could not be touched by Satan because He was the Son of God. Verse 19 lets us know only two types of people exist in the world according to John: children of God and children of Satan. One belongs either to God or to the evil world system that is Satan’s domain. Because the whole world belongs to Satan, Christians should avoid its contamination. If you do not know Christ as your your Savior today I ask you to find a pastor or friend who is saved to tell you how to become a child of God.
