Hah! I was just talking with someone about this. I said I had actually come to like the testing of my trust. How could you not come to like what makes your feet more sure and steady?
I Love how Paul shows here that this Patience we learn then leads us to be vessels of spreading the love of God to others.... Reminds me of 1 corinthians 13, "Love is patient". (1 Corinthians 13:4)
