God promised to to save human beings who believe in his only begotten Son before this heaven and earth perishes by fire on the Last Day (Isaiah 24:1, 19-20) (Revelation 11:18, 20:11).
“[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).
“[TAKE HEED, BRETHREN, LEST THERE BE IN ANY OF YOU AN EVIL HEART OF UNBELIEF, IN DEPARTING FROM THE LIVING GOD]. But exhort one another [DAILY], while it is called To day; lest any of you be hardened through the deceitfulness of sin. For [WE ARE MADE PARTAKERS OF CHRIST], if we hold the beginning of our confidence stedfast [UNTO THE END]” (Hebrews 3:12-14).
