God's word made us to understand that it is already appointed unto man once to die and after that follows judgement.
God's word also made us to understand that heaven and earth will surely pass away but that of Gods word remains and stands sure no matter the situation. God never changes from his word.
Now in as much as we have understand that death is what everyone will pass through,then we should not been seen as people who are perturbed about death.
But what should matter much is the life we have live for the little time here on earth, we must do Gods will and always keep abiding to Gods commandments knowing that fully one day we shall all leave this earth and stand before the kings of kings to answer questions on how we have spent our days on earth.
GOD BLESS HIS WORD
AMEN
