16 Go, gather together all the Jews that are present in Shushan, and fast ye for me, and neither eat nor drink three days, night or day: I also and my maidens will fast likewise; and so will I go in unto the king, which is not according to the law: and if I perish, I perish.
Esther 5 1 Now it came to pass on the third day, that Esther put on her royal apparel, and stood in the inner court of the king's house, over against the king's house: and the king sat upon his royal throne in the royal house, over against the gate of the house.
2 And it was so, when the king saw Esther the queen standing in the court, that she obtained favour in his sight: and the king held out to Esther the golden sceptre that was in his hand. So Esther drew near, and touched the top of the sceptre.
3 Then said the king unto her, What wilt thou, queen Esther? and what is thy request? it shall be even given thee to the half of the kingdom.
I have noticed that you have utilized Genesis 8:21-22 as your definitive passage, and used it to interpret all the rest of Scripture. I believe that you have thus placed the cart before the horse. Rather than allowing an isolated passage of Scripture to interpret the rest of Scripture, one must always allow the overall mesage of Scripture to interpret individual passages.
As a result, God is saying in Genesis 8 that he will never again destroy the earth in the same manner as the flood. This is the meaning that Peter assigns, as witnessed by II Peter 3:1-15. This is only one of many passages that describe the final consummation of the history of this earth, and the promise of a "new heaven and new earth to come. This is the "world without end" (Isa 45:17; Eph 3:21), a world that has been purified by fire and no longer bears the stain of sin.
