Thank you for taking my eternal life

Yesterday, some of my church friends and I were having a gathering, and many members of our church are doing their daily devotional time through the "Eternal Life Devotional", which is a print done by a Korean church.

As one of my friends did not attend service on Sunday, one of us collected on his behalf and passed it to him yesterday. And this is what he said:

"Thank you for taking my eternal life."

To a layman passerby, he would think that he was dead, because someone had taken his eternal life.

But this prompted me to think of something else, which is how with the "technologically saturated childhood", we are beginning to increasingly ellipsis phrases and words, and even, to take them in the figurative sense literally. I started wondering if in time, the dictionary would even be redundant in daily social life, since everyone seemingly create a new word class with their own terms of sense or referent.

In time, would the mental lexicon be THE dictionary that people trust? If that is the case, then it would be quite sad.
