Of course the obstacles get larger as you race the course. You are better equipped than when you were at the starting line. You have Power which was unavailable before, and the further you advance on the course, the more you will face the ‘impossible’ which will leave you no choice but to draw on that Power.
Giving up is not an option. I won’t let you give up until you have completed your purpose. Don’t worry about how or when or why - focus on the task at hand today. I will take care of the rest.
