When doubt creeps in after you start following God, cry out to him in prayer. The Israelites' escape from Egypt began when they cried out, and that same practice will carry you through your struggles now.
Or remember, you started out with boldness and now you have a little bit of doubt. Is this the plan of God for me? Whenever you find yourself in this situation, the answer here is to cry out to God. Remember, the only way that the Israelites are finding themselves out of Egypt to begin with is because in Exodus chapter 1, 2, and 3, they cried out to God. So the thing that got you out of Egypt is the thing that's going to keep you out of Egypt. Cry out to God. This is why I keep reiterating the importance of prayer.
