One more Lewis.
The best part of being a Christian is knowing that better things are ahead. We are promised the greatest reward out there: eternal life with Jesus in the best place ever in complete joy without any suffering at all.
As long as we stay focused on that far into the future, we can’t go wrong. Things will happen here on Earth that are going to bring us pain and struggles, but we will leave all of them behind. Just drop them and go.
Why not do it now? Why worry? Live life. Yearn for better things.
