Toni, even the apostle Paul lived with some kind of physical challenge [in 2Corinthians 12]. This verse is the best:
And He has said to me, "My grace is sufficient for you, for power is perfected in weakness." Most gladly, therefore, I will rather boast about my weaknesses, so that the power of Christ may dwell in me.
I can completely understand about usually leaving off the challenges we face. I am also one of those that leaves out the stuff that may be a downer-not because I don't want you all to know or because it is bad stuff-mainly because I come here to be about something "not" about me or my usual little world. I am learning to share more and ask for prayer. When things are tough is usually when I don't have much time to be on the computer too. Does that makes sense?
