"Let us return into Egypt!"

This evening I've been working on my Sunday school lesson for tomorrow morning. It's over Numbers 13 and 14 and the phrase "Let us return into Egypt" (14:4) really stuck out to me. How many times in our lives as Christians do we only see the giants and obstacles ahead of us? How many times is our focus so much on those obstacles that we would rather return to the slavery of Egypt than to press forward? Think of what God was offering the Israelites: a developed country of their own with fortified cities and abundant crops. Not only that, He had also promised that He would fight for them and give them the land. But, in the moment when they needed to trust His promises, instead they focused on the obstacles. They focused so much on the obstacles that they limited themselves in their effectiveness and eventually, they never made it to the promised land.
How about us? What great task does God have ahead of us that He has promised to help us to accomplish? What battle, as it were, faces us that He has promised to help us win? Will we trust His power and His authority and His promises? Or, will we sell ourselves, and also God, short and rather stagnate in our Christian life than press forward and accomplish great things through His all-sufficient power?
