This is a diagram of several Bible verses, which run, in the RSV, "More than that, we rejoice in our sufferings, knowing that suffering produces endurance, and endurance produces character, and character produces hope, and hope does not disappoint us, because God's love has been poured into our hearts through the Holy Spirit which has been given to us." (Romans 5:3-5) It's kind of a hardcore, suck-it-up kind of verse, but I like it anyway. It's one of those ones I tend to remember when things go wrong (although when things go really really wrong, it also makes a handy hammer to beat myself over the head with: I apparently need more suffering or I'm never going to develop any character, much less hope.).
