Thematic Bible: What shall be tried

[the quality of] each person's work will become evident [i.e., for what is it made of]. For the [judgment] day will expose his workmanship. And it will be revealed by the fire [of judgment], which will test the quality of a person's workmanship [i.e., the faithfulness of his converts]. If the work of anyone lasts [i.e., if his converts are judged faithful], he will receive a reward [i.e., his converts will constitute part of his reward]. But if anyone's work is burned up [i.e., does not survive the judgment], he will experience loss [i.e., of his converts], but he himself will [still] be saved, like a person escaping from the fire [i.e., of a burning building, which consumes his efforts].

"And write [this] to the angel of the church at Philadelphia: These are the words of Him who is holy and true, [and] who possesses the key [i.e., the power and authority] of King David, [and] who opens [a door] which no one will close, and who closes one that no one will open: I know about your deeds. (See, I have placed before you an open door, which no one can close). [Note: This probably refers to their being assured of some unspecified opportunity]. [I know] that you have [only] a little bit of strength, but [in spite of that] you have obeyed my word and did not deny my name. Look at those who belong to the synagogue of Satan [See 2:9]; they claim to be Jews, yet they are not, but are lying. Watch, I will make them come and bow down at your feet [in respect] and [they will] know that I have loved you. read more.
Because you have obeyed my command to remain steadfast [in the face of difficult times], I will also keep you from [giving up when] the time of trial comes, which is about to come upon the whole world, to test those living on the earth.
