Luke 22:42 - "Father, if you are willing, take this cup from me; yet not my will, but yours be done."
Philippians 4:13 is very well known - "I can do all things...". I think that's the King James Version - some more recent versions seem to suggest something more like "I can get through anything" instead. So it's not so much like "I can leap tall buildings at a single bound", so much as "I will survive." Personally, I prefer the first option.
Jesus showed us both. He healed people. He fed people. He did supernatural things. But as well as that, he coped with everything that came at him. He handled the storm, the temptation, the tricky questions. And here in today's verse, we see Jesus faced with the problem of going to the cross. He would've wanted to have said "I can't do this", but because he had the power of God within him, just as we do, he knew that he could get through it. But as well that, I think he also knew that he could do the incredible task that was ahead of him. This wasn't just something that was coming his way - it was the task that he had become man for.
When things come our way, let's remember that we can get through all things. But let's also not fear doing those things for which we may need supernatural strength.
