We can find ourselves facing something and feel we are completely powerless to avoid it or go through it ("it" being whatever it is you're facing). I know I'm doing that now. And I must admit that my "it" is rather large and could be very, very bad; but, only if I grow weak and not trust Him. So, we persevere and move along in our walk and always trust Him to see us through.
Philippians 4: 13 "I can do all things through Christ which strengtheneth me." After I quote this verse I always ask what I believe to be the most logical question: "But, do you want too?"
