Beloved, now we are children of God, and it is not yet revealed what we will be. But we know that, when he is revealed, we will be like him; for we will see him just as he is.
That when he appears --  "he" or "it" ? PPT: "The context is strongly in favour of "it," i.e., "if it shall be manifested what we shall be;" <620228> 1 John 2:28 1 John 2:28 seems to favour "he," i.e., "if Christ shall be manifested." The context must prevail." RWP: "The subject may be Christ as in 1 John 3:9, or the future manifestation just mentioned. Either makes sense, probably “it” here better than “he."
