When you buy a puzzle, you see the end vision of what it can be by looking at the box, but then you dump it out and you have to get there by putting all of the pieces together. Every time you put another piece in place, it makes it easier for the next piece because there are fewer pieces left and you are starting to see the image on the box. Similarly, when you are given a vision of something grand by God, you see what is possible --- you see the completed image. You don't know yet what the pieces are or how they fit together, but you know that God will give you all of the pieces when you need them. As you begin to put them in place, the direction you need to go, the piece you need next, is revealed to you, and you can really see the finished project coming together. Know that when you are given a vision, it is always possible, even if you have no idea how you will get there, which is the case for most people. Trust that all of the pieces will be given at the appropriate time, for a piece of the puzzle cannot go into place until the pieces around it are in place.
