1 John 5:4-5
For whatsoever is born of God overcometh the world: and this is the victory that overcometh the world, even our faith. Who is he that overcometh the world, but he that believeth that Jesus is the Son of God?
John reveals the secret of victory over the world. The world system is a scheme of temptation, always trying to drag us away from God and from what is eternal, and seeking to occupy us with what is temporary and sensual. Only the one born of God overcomes the world, because by faith we are able to rise above the things of this world and see things in their lives from an eternal perspective. The one who overcomes the world is the believer who realizes that the things which are seen are temporary and the things which are not seen are eternal.
