Thematic Bible: Who overcomes the wicked

I am writing to you fathers, because you have known Him [i.e., Christ], [who has existed] from the beginning [See John 1:1]. I am writing to you young men, because you have overcome the [power of the] evil one [i.e., through faith they had gained victory over Satan, See 5:4]. I have written to you little children [i.e., dear ones], because you have known the Father [as your God]. I have written to you fathers, because you have known Him [i.e., Christ], [who has existed] from the beginning. [See verse 13]. I have written to you young men, because you are [spiritually] strong and the word of God continues to live in your hearts, and you have overcome the [power of the] evil one [See verse 13].

Loved ones, do not believe [the message of] every spirit [i.e., every person claiming to be a teacher], but test the spirits [i.e., require proof that they and their message are genuine] to see whether they represent God [or not], because many false prophets have begun circulating throughout the world. Here is how to know [who is speaking from] the Holy Spirit of God: Every spirit [i.e., person] who proclaims that Jesus Christ has come [to earth] in a physical body is [speaking] from God. [See I Cor. 12:3]. But every spirit who does not proclaim [this truth about] Jesus is not [speaking] from God. And this [person] represents the spirit of the antichrist [See 2:18-22; II John 7], whom you have heard would come. Well, now he is already here! read more.
[But], you people are [followers] of God, little children [i.e., dear ones], and you have overcome them [i.e., these false teachers] because He who is in your lives [i.e., the Holy Spirit, See 3:24] is greater [i.e., more powerful] than he who is in [i.e., dominates] the world [i.e., Satan. See II Cor. 4:4].
