“The righteous perisheth, and no man layeth it to heart: and merciful men are taken away, none considering that the righteous is taken away from the evil.” Isaiah 57:1 (KJB)
First of all we need to understand who the righteous are. The righteous are those whom God declares righteous, and none other. In the context of Scripture these righteous are a remnant of Israel who were ashamed of the sin, debauchery, and evil in the land, and they kept themselves from it. The righteous of today are those who have been redeemed by the blood of Jesus Christ death on the cross; His burial and resurrection proving the deal.
The death of the righteous is just as likely as the death of the evil. It is most likely going to happen, and none knows the day. The death of the righteous is not eternal. The death of the wicked is eternal. There is a place in Heaven prepared for the righteous. There is no place found for the evil in Heaven, so the only place for them is Hell.
When the righteous die there will be many wicked who applaud that death saying something like “Well that trouble maker is gone, and good riddance”, maybe just thinking it. The wicked always see the righteous as the cause of trouble. At any rate they do not care at their passing.
The merciful are the same as the righteous, and will be taken away from the evil that God has declared judgment upon. God knows how to deliver the righteous from the evil…
“The Lord knoweth how to deliver the godly out of temptations, and to reserve the unjust unto the day of judgment to be punished…” 2 Peter 2:9
Become one who is righteous before God. Call on the name of the One who died on the cross for you, was buried, and He rose again. His name is Jesus Christ the Son of God, God the Son.
