“Whereof I am made a minister, according to the dispensation of God which is given to me for you, to fulfil the word of God” (Colossians 1:25).
Second Timothy 2:15 is the only verse in a King James Bible that tells us to “study” Scripture. (And you need a King James Bible to have that word “study!”) Not only so, 2 Timothy 2:15 also tells us how to study Scripture. We let the verse speak for itself: “Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.” Please draw your attention to the phrase, “rightly dividing the word of truth.”
Immediately after the exhortation to “study… rightly dividing the word of truth,” a warning appears in verse 16: “But shun profane and vain babblings: for they will increase unto more ungodliness.” What are these “profane and vain babblings”—these evil, empty, nonsensical words—that we should avoid? Verses 17 and 18 do not leave us to wonder: “ And their word will eat as doth a canker: of whom is Hymenaeus and Philetus;  Who concerning the truth have erred, saying that the resurrection is past already; and overthrow the faith of some.”
Since they did not “rightly divide the word of truth,” Hymenaeus and Philetus were guilty of a grave error. They said the “the resurrection is past already.” By doing this, they overthrew the faith of some Christians. The words “past already” in verse 18 convey the idea of a timeline or schedule. These hereticks claimed the Rapture (resurrection of Christians in the Church the Body of Christ) had already occurred. Their audience was forced to conclude that, with the Rapture passed, they were living in Israel’s prophetic program (the wrath of God, commonly called “the seven-year Tribulation”).
It was a most serious error. Hymenaeus and Philetus were not dividing the household rules God had given the Body of Christ through Paul, from the household rules God had given the nation Israel through her apostles and prophets. As professing “Christianity” shows us today, such a blurring or removal of dispensational boundaries still makes the Bible confusing and burdensome.
They had better heed today’s Scripture… source
