Fear. What are you really afraid of? Compare your fears to God. How small are your fears compared to God? God fights for you, so what do you have to fear?
NOTES ON THE TEXT
Verses 12-17 is of Moses dividing up the land that they possessed after defeating Sihon the king of the Amorites and Og the king of Bashan, among the tribes of Reuben, Gad, and the half-tribe of Manasseh. They possessed all the land east of the Jordan, and they weren't done yet.
21 And I commanded Joshua at that time, 'Your eyes have seen all that the LORD your God has done to these two kings. So will the LORD do to all the kingdoms into which you are crossing. 22 You shall not fear them, for it is the LORD your God who fights for you.
Although, they possessed all the land east of the Jordan, they weren't finished. God's promise to Abraham and his descendants was the Promised Land, not the land to the right of the Promised Land. There were still enemies to face, enemies to conquer, and land to be possessed. As God fought with them against Sihon and Og, God would be with them against any other enemy. This was not going to be an easy task, but who said following God or His will would be easy?
Fear. If you give it the power to, fear can cripple you. What are some of your fears? Failing? Rejection? The future and whether you'll get into a "good" school, graduate, and get a "good" job?
There are so many things that we can be fearful of, but what is actually worth it? Most of the things that we're afraid of scenarios that we make up in our minds. Also, here's a question to ask yourself whenever you feel fear creeping up on you. If you fail a class, or get rejected from every "good" school you applied to, or work someplace you said you'd never work at, does God love you any less? Does God stop fighting for you? Does God take back the blessings He already bestowed upon you? If you're struggling to answer these questions, it's simple. NO!!! God doesn't require you to pass every class, or get into a "good" school. Following God is more simply said than done, but God just wants all of you. God, the creator of you and me, and the world we live in, fights for you. What do you possibly have to fear except God himself?
