Deuteronomy 9:1
"Hear, O Israel: Thou art to pass over Jordan this day, to go in to possess nations greater and mightier than thyself, cities great and fenced up to heaven,"
When you look at how Israel conquered Canaan, you would have to admit that it was an unbelievable task. Israel was a people who had no training ground for their military. They had no place to build fortresses in which to defend themselves. They went up against armies that were feared by everyone; yet, they did the unbelievable and conquered the land of Canaan.
In the verse above, God reminded them that they would go in an "possess nations greater and mightier" than they. God reminded them that they would have to go up against cities that had walls to defend themselves. Yet, God also reminded them that He was on their side, and that He would help them fight these great battles.
Christian, God can still do the unbelievable today. What the world thinks cannot be done can be done if a person will get God on their side. Just like Israel went in and conquered cities and nations mightier than they, you can conquer the unbelievable in your life if you will only believe that God can still do the unbelievable.
If you are going to do the unbelievable, then you are going to have to have faith in God. Verse 3 says, "Understand therefore this day, that the LORD thy God is he which goeth over before thee;..." When God tells you to do something, you must by faith trust God that He will do what He says He will do. It took faith for Israel to go up against these cities and nations. They were literally putting their lives on the line. That is great faith. You will never do the unbelievable if you don't exercise faith. Faith will many times want you to put everything on the line, but you have to trust that God will come through. If there is no risk, then there is no faith, yet if God tells you to do something, then there truly is no risk in your faith for God will come through.
Second, you must take the first step before God helps you do the unbelievable. I know that is faith, but many times people believe God needs to do something first before they completely step out. God wants to see if you are all in. He wants to see if you truly have faith in Him. Once you are all in and take that first step of faith to attempt the unbelievable for God, then He will step in and make the unbelievable happen.
Finally, you will not have to attempt the unbelievable alone. If God told you to do something that seems unbelievable, then you can rest assured that He will be there with you. God told Israel in verse 3, "Understand...that the LORD thy God is he which goeth over before thee;..." God did not let them go alone, He went with them. You never have to do the unbelievable alone, for if God told you to do it, He will be there with you to make it happen.
Christian, what is it that God has asked you to do that seems unbelievable? Always remember that God will never ask you to do something that He won't provide the wherewithal to do. He will be there for you. All you have to do is have faith in Him and step out. Once you step out, you will find that God will come through.
