After Noah and his family came out of the ark after the great flood, God promised that the earth will not perish again by a great flood. God declared to Noah:
“[I DO SET MY BOW IN THE CLOUD], and it shall be for a token of a covenant between me and the earth. And I will remember my covenant, which is between me and you and every living creature of all flesh; and the waters shall no more become a flood to destroy all flesh” (Genesis 9:13, 15).
God promised to to save human beings who believe in his only begotten Son before heaven and earth perishes by fire on the Last Day.
“[FOR GOD SO LOVED THE WORLD, THAT HE GAVE HIS ONLY BEGOTTEN SON, THAT WHOSOEVER BELIEVETH IN HIM SHOULD NOT PERISH, BUT HAVE EVERLASTING LIFE]. For God sent not his Son into the world to condemn the world; but that the world through him might be saved” (John 3:16-17).
“[FOR THE PREACHING OF THE CROSS] is to them that perish foolishness; but unto us which are saved it is the [POWER OF GOD]” (1 Corinthians 1:19).
“[WHEREBY THE WORLD THAT THEN WAS, BEING OVERFLOWED WITH WATER, PERISHED]: But [THE HEAVENS AND THE EARTH, WHICH ARE NOW], by the same word are kept in store, [RESERVED UNTO FIRE AGAINST THE DAY OF JUDGMENT] and perdition of ungodly men” (2 Peter 3:6-7).
“[THE LORD IS NOT SLACK CONCERNING HIS PROMISE], as some men count slackness; but is longsuffering to us-ward, not willing that any should perish, but that all should come to repentance.
But the day of the Lord will come as a thief in the night; in the which the heavens shall pass away with a great noise, and the elements shall melt with fervent heat, the earth also and the works that are therein shall be burned up.
Seeing then that all these things shall be dissolved, what manner of persons ought ye to be in all holy conversation and godliness, Looking for and hasting unto the coming of the day of God, wherein the heavens being on fire shall be dissolved, and the elements shall melt with fervent heat?” (2 Peter 3:9-12).
“Nevertheless we, according to his promise, look for new heavens and a new earth, wherein dwelleth righteousness. Wherefore, beloved, seeing that ye look for such things, be diligent that ye may be found of him in peace, without spot, and blameless” (2 Peter 3:13-14).
“The grace of our Lord Jesus Christ be with you all. Amen” (Philippians 4:23).
