Dearly loved ones, we are God's children now, but it has not yet been revealed [to us] what we will be [in the future life, Luke 20:34-36]. But, we do know this, however, that when Jesus is revealed [i.e., at His second coming], we will be like Him [I Cor. 15:49], for we will see what He really looks like!

But, you [should] know that Christ appeared [on earth] to take away [our] sins, and that there is no sin in His life [See II Cor. 5:21].

And God lives in the heart of the person who [continually] obeys His commands, and he lives in [fellowship with] God. And here is [another] way we know that God lives in our hearts: It is by [means of] the Holy Spirit, whom God gave to us. [See Rom. 8:9, 11; James 4:5; I Cor. 6:19].

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], 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].
