Sometimes in your journey to fulfill a set vision there are numerous challenges. You may even think of abandoning the vision along the way or even at inception. Jericho city was so fortified but God said to Joshua, "See, I have given into thine hand Jericho". He wants you to see it first. You capture first within you, in your mind. Let your mind synthesize images where you own the land, where you have achieved the vision or milestone. This happens as you meditate. Don't see failure. Note that He says, "I have given" not He is about to do it, meaning it's done. God wants you to see that you have achieved. If you can't see first in heart and mind then your physical feet can't trample there. Through meditation on God's word you construct positive images. See that the land is given to you. See possibilities and refuse to give up.
