You were doing a good job until you tried to show Deuteronomy 4:30 applying to NT saints. Lets put Deuteronomy 4:30 in context:
Deuteronomy 4:25-31
25 "When you become the father of children and children's children and have remained long in the land, and act corruptly, and make an idol in the form of anything, and do that which is evil in the sight of the LORD your God so as to provoke Him to anger, 26 I call heaven and earth to witness against you today, that you shall surely perish quickly from the land where you are going over the Jordan to possess it. You shall not live long on it, but shall be utterly destroyed. 27 And the LORD will scatter you among the peoples, and you shall be left few in number among the nations, where the LORD shall drive you. 28 And there you will serve gods, the work of man's hands, wood and stone, which neither see nor hear nor eat nor smell. 29 But from there you will seek the LORD your God, and you will find Him if you search for Him with all your heart and all your soul. 30 When you are in distress and all these things have come upon you, in the latter days, you will return to the LORD your God and listen to His voice. 31 For the LORD your God is a compassionate God; He will not fail you nor destroy you nor forget the covenant with your fathers which He swore to them. NAS
This applies only to the Jews since we are now living in the later days, which started before John wrote his espistles. Have you studied Ezekiel, especially chapter 37?
I would hope that those who read your post will put the Scriptures you quoted into context and draw their own conclusions based on knowledge, discernment, and wisdom instead of assumptions based on your concept of duality of interpretation.
