We declare to you what we have seen and heard [concerning Christ], so that you also may share a relationship with us. And indeed, our fellowship is with the Father and with His Son Jesus Christ.

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!

The person who [sincerely] believes in God's Son has the evidence [of it] within his heart, [confirming God's testimony]. The person who does not believe God [i.e., what He says about Jesus], accuses Him of lying, because he has not accepted the [irrefutable] testimony of God concerning [the identity and mission of] His Son.
