There are little words to explain the despair felt when a loved one
passes away, for any reason. No matter the culture, religion, gender, ethnicity, or nationality, the feeling one experiences is universal. The phrase 'may he rest in peace' is also universal, however may or may not be relevant.
Peace
Peace is defined as the non-warring condition. It is the end of hostilities. Peace is a state of mutual harmony. It is freedom from commotion and violence; it is order and security. No strife, no dissension; no discord. A state of tranquility.
Can We Prepare to Rest in Peace?
We can prepare to rest in peace, however preparation to rest in peace is a lot different from preparing for weddings, anniversaries, etc. Its definitely more than making funeral arrangements or purchasing plots. To prepare to rest in peace is to make peace with God.
How do We make peace with God?
Accepting Jesus Christ as Lord and Savior of our life is assuring that our rest be in peace. "For God so loved the world, that He gave His only begotten Son, that whosoever believes in Him should not perish, but have Everlasting Life (John 3:16)." Believers will be ushered into an eternity with God; a rest in Peace. "And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away (Revelation 21:4)."
The biblical record is clear that God is going to judge every person, “And just as it is appointed for man to die once, and after that comes judgment…” (Hebrews 9:27).
Make Peace with God.
