Dispensationalism stands on the literal, historical, grammatical hermeneutic.
2P2P is recognized in the Scripture as a result of this hermeneutic.
If one departs from that hermeneutic and begins to interpret Scripture with a basically allegorical hermeneutic, particularly with regard to prophecy, then 2P2P is no longer recognized in Scripture and it only seems that Dispenstionalism falls apart.
Dispensationalists believe the Scriptures as written.
Allegoricists import and impose a foreign meaning on Scripture. Those who believe what the Allegoricists say the Scripture means must place their faith in the self-proclaimed authority of the Allegoricist rather than just reading Scripture to discover what it plainly says. If Scripture is literal then most readers will come to basically the same understanding. If Scripture is to be understood allegorically, then the reader must go to the Allegoricist to discover what it means. I think that GOD meant for people to read and understand plainly what it means.
Ok read plainly what it says.
Eph 5:23 For the husband is the head of the wife, even as Christ is the head of the church: and he is the saviour of the body.
Eph 5:24 Therefore as the church is subject unto Christ, so let the wives be to their own husbands in every thing.
Eph 5:25 Husbands, love your wives, even as Christ also loved the church, and gave himself for it;
Eph 5:26 That he might sanctify and cleanse it with the washing of water by the word,
Eph 5:27 That he might present it to himself a glorious church, not having spot, or wrinkle, or any such thing; but that it should be holy and without blemish.
Eph 5:28 So ought men to love their wives as their own bodies. He that loveth his wife loveth himself.
Eph 5:29 For no man ever yet hated his own flesh; but nourisheth and cherisheth it, even as the Lord the church:
Eph 5:30 For we are members of his body, of his flesh, and of his bones.
Eph 5:31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
Eph 5:32 This is a great mystery: but I speak concerning Christ and the church.
2Co 11:2 For I am jealous over you with godly jealousy: for I have espoused you to one husband, that I may present you as a chaste virgin to Christ.
2Co 11:3 But I fear, lest by any means, as the serpent beguiled Eve through his subtilty, so your minds should be corrupted from the simplicity that is in Christ.
2Co 11:4 For if he that cometh preacheth another Jesus, whom we have not preached, or if ye receive another spirit, which ye have not received, or another gospel, which ye have not accepted, ye might well bear with him.
2Co 11:5 For I suppose I was not a whit behind the very chiefest apostles.
