17-18: “If thou shalt say in thine heart, These nations are more than I; how can I dispossess them? 18 Thou shalt not be afraid of them: but shalt well remember what the Lord thy God did unto Pharaoh, and unto all Egypt;”
Main Point: In times of doubt, look back at the victories God has already won.
Moses is encouraging the people about taking over the Promised Land. He understands that there will probably be times when they get scared and doubt the promise and power of God and wonder if they can really defeat all the powerful and established nations in Canaan. Moses encourages them to, in times like these, look back to times like Egypt where God set them free from such a huge and powerful nation. It was all supernatural, all the hand of God. This is how it would be in Canaan as well. God would be the one doing the work. He would be fighting for them. They were simply to remember how powerful God is, remember what they know about Him, and put their faith in Him. They would ask themselves if they could do it and the answer was “no,” but God could and He had won similar victories before.
I need to remember this. It is not me accomplishing anything. In ministry, in life, I am not the one working and accomplishing success. It is God. When I begin to doubt what I can accomplish, look to God and see what He has already accomplished in my life. Know that He is the one at work, He is in control. Put my faith and trust in His power and His work. It is not me at all.
This is a picture of the gospel. The power behind the gospel is not what I can bring to the table and what I can accomplish. The power of the gospel is the power of God. He is the Savior, He is the sacrifice, He is the justifier. Nothing of my salvation is of me. I do not accomplish salvation for myself, it is all a work of God.
