'Victorious' in the Bible

I am writing to you, fathers [those believers who are spiritually mature], because you know Him who has existed from the beginning. I am writing to you, young men [those believers who are growing in spiritual maturity], because you have been victorious and have overcome the evil one. I have written to you, children [those who are new believers, those spiritually immature], because you have come to know the Father.

I have written to you, fathers, because you know Him who has existed from the beginning. I have written to you, young men, because you are strong and vigorous, and the word of God remains [always] in you, and you have been victorious over the evil one [by accepting Jesus as Savior].

For everyone born of God is victorious and overcomes the world; and this is the victory that has conquered and overcome the world—our [continuing, persistent] faith [in Jesus the Son of God].

Who is the one who is victorious and overcomes the world? It is the one who believes and recognizes the fact that Jesus is the Son of God.
