This Jesus is the one whose coming [to earth was introduced] by water [at His immersion. See Matt. 3:13] and [completed] by blood [at His crucifixion, John 19:17-37]. He did not come by the water only, but by the water and by the blood. And it is the Holy Spirit who gives testimony [at both of these events], because the Holy Spirit is [always] the truth. [See John 16:13].

And now, my children, keep your hearts in him; so that at his revelation, we may have no fear or shame before him at his coming.

My loved ones, now we are children of God, and at present it is not clear what we are to be. We are certain that at his revelation we will be like him; for we will see him as he is.

Let therefore abide in you that same which ye heard at the beginning. If that which ye heard at the beginning shall remain in you, then ye also shall continue in the son, and in the father.
