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.
The word to know, shews the certainty of faith, in order to distinguish it from opinion. Neither simple nor universal knowledge is here intended, but that which every one ought to have for himself, so that he may feel assured that he will be sometime like Christ. Though, then, the manifestation of our glory is connected with the coming of Christ, yet our knowledge of this is well founded.
