What scripture says so?
Doesn’t it stand to reason that He only operated that way in the first century too?
What scripture makes it clear that His operation changed from active to passive; from literal to figurative?
If His dwelling within the believer is figurative now but used to be literal, when did it change? What scripture makes this clear?
Are the promises regarding the Holy Spirit really different for people now than they were then? Does He no longer distribute any kind of spiritual gifts? Or any of the other aids mentioned in this previous post? If He does provide some but not all, which ones? How can one tell from scripture; which passage differentiates them?
If His dwelling within is figurative and always has been, how does He help believers through the written word only but in ways that only a living, present Person could (such as intercession in prayer)?
How much other scripture is figurative and not literal? How can we as readers know when God does not really mean what He says?
These are questions that beg an answer if the Spirit-in-the-written-word-only-today doctrine is to be taken seriously.
