The Sea Will Be No More?

In this episode, Dr. Betters answers the question, "Revelation 21:1 speaks about a new heaven and a new earth, and the sea was no more. This has always puzzled me. I keep in mind Noah and the flood. And in Romans 8:22 where the earth groans from sin. The thought came to me as to why the 'sea will be no more.' Is it because the ocean is a reminder of man's sin and the penalty of the flood? My question is more of 'Biblical curiosity.' I do not fear the future for I know my Redeemer and He lives in me and I am SEALED, praise God. Thank you for your ministry, and keep on keeping on, God bless. Howard”
