Last night before I went to sleep I "just happened" to read 2 Corinthians 4:7-18. That was God's encouragement to me on the issue of death envy.
It doesn't make the problem easier, and it doesn't make the problem go away, but it does make it make sense, which is critical for me.
I would suggest reading it in several translations such as the NLT, NIV, and ESV to get a fuller sense of it. (The different colored texts are links you can click on...)
