Rather, Scripture is what is lacking in your so called defense. Gn. 1 clearly states that man and women were created on the 6th day, and which Christ references as being so, and ties Gn. 1:26,27 in with Gn. 2:24. Gn. 1 states that that all creation was finished on the 6th, and multiple texts affirm this. Meanwhile ‘But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day" (2 Peter 3:8) is a simile, not literal, and if you want to make it literal then since a thousand years is as one day then the millennial reign of Christ will only be one day. However, what this simile teaches that God is not bound by time. And since you deny what is plainly written and misunderstand the summary supplementary nature of Gn. 2 then it is you who is an author of confusion. Repent.
Who gave you the authority to degrade the words of Peter ... Here is how Peter opened this chapter...
3:1 This second epistle, beloved, I now write unto you; in both which I stir up your pure minds by way of remembrance: 2 That ye may be mindful of the words which were spoken before by the holy prophets, and of the commandment of us the apostles of the Lord and Saviour:
Then Peter lays out the THREE heaven and earth ages .. What was, what is now and what will be ..
Peter teaches us the methodology of how the Heavenly Father marks 'time'...
8 But, beloved, be not ignorant of this one thing, that one day is with the Lord as a thousand years, and a thousand years as one day.
You have exposed yourself to be one of those that fit into the Deuteronomy 4:2; Deuteronomy 12:32 and Revelation 22:18 For I testify unto every man that heareth the words of the prophecy of this book, If any man shall add unto these things, God shall add unto him the plagues that are written in this book:
As it is Written, Christ came in the volume of the 'BOOK'.
Nothing Peter penned regarding the means and methods of How the Heavenly Father marks time changes anything regarding the 'Lord's Day that begins on the day Christ return. ... Why John was taken in the Spirit to the Lord's Day, in Revelation.
