At the end of Cassie’s earthly life, we were talking, and I told her that once she gets to heaven, she’d have no more pain and that she’d think clearly than she ever had before. I believe this devotional by Pastor Greg Laurie sums it up pretty much.
“Our bodies are buried in brokenness, but they will be raised in glory. They are buried in weakness, but they will be raised in strength. They are buried as natural human bodies, but they will be raised as spiritual bodies. For just as there are natural bodies, there are also spiritual bodies.”
1 Corinthians 15:43–44
