It's important to remember death, and in the right way, in the truth. It's really obscene to lie where death is concerned - even if it's lying by forgetting and averting our eyes.
I was reading in Second John today how clearly loving one another depends entirely on living in the truth. Love rejoices in the truth (1 Corinthians 13:6). As far as we have an argument with truth, we're not really going to love anybody. Indeed, Sentimentality = Love - Truth.
And sentimentality is cruel, just as it is written: "The tender mercies of the wicked are cruel."
So as Spock said to McCoy in the Star Trek movie: "Remember!"
