"For everyone born of God overcomes the world. This is the victory that has overcome the world, even our faith." (1 John 5:4)
Who overcomes the world?
Those who are born into God's family through faith (believing that Jesus is the Son of God and trusting Him as Lord and Savior)!
Our regeneration along with faith in Jesus Christ gives us victory that has overcome the world. Those who love God and obey God rather than following the way of the world are world overcomers. To overcome the world is to be victorious over its sinful patterns of life. Our (God-given) faith (God-confidence that overcomes fears & doubts) and the indwelling Holy Spirit empower us to live a life of obedience to God and to have daily victory over the world (overcoming the sinful, carnal ways of the world). And when the world tries to knock us down and discourage us, faith in Jesus will help us get back up and keep on keeping on. We are more than conquerors through Christ who loves us! "I have told you these things, so that in Me you may have peace. In this world you will have trouble. But take heart! I have overcome the world." ~Jesus (John 16:33)
"The world gains the victory over the unregenerate by captivating their affections and capturing their wills. But the Christian overcomes the world, because his affections are set upon Christ and his will yielded to Him.
Here--then, we have a sure criterion by which we may determine our Christian progress or spiritual growth. If the things of this world have a decreasing power over me--then my faith is becoming stronger. If I am holding more lightly the things most prized by the ungodly--then I must be increasing in an experimental and soul-satisfying knowledge of Christ. If I am less cast down when some of the riches and comforts of this world are taken from me--then that is evidence they have less hold upon me." (Arthur Pink)
"Growth in faith will be manifested by increasing deadness to the world. The more faith discovers of the beauty and glory of the Savior, and the splendors of that heavenly country to which the Christian is bound--the more worthless will this world appear!" (William Nicholson)
