Luke 22:8-12 (NKJV)
When you are traveling somewhere or you have a goal to reach the main thing is to get to the destination and reach that goal. All of the steps between where you start and where you end are not as important as the final objective, but those steps are still important. Without taking the necessary steps to move forward you would never get to where you need to go. This is a problem area for some people in following God's direction, they want the end result without having to take the steps in between the start and the finish.
In Luke 22 we see Jesus sending Peter and John to a city to find the place to prepare the Passover. The goal was the place where they could meet, going to the city was a step in the right direction but it was not the only step. Jesus told them to locate a certain man, but that was not the final step. The man with the pitcher was only leading Peter and John to the place where they would meet another man who would then take them to their final goal. But what if Peter and John had skipped a step or two, would they still have gotten the same result?
We will often find that God directs us into one thing that brings us into something else; God gives us one step that leads to another. This is not to say that we view the things we do or the people we meet as just stepping stones we use to achieve a goal, that is not right at all. But as God brings us opportunities to take steps in our walk with Him we must realize that God has a plan and He is working to develop us, prepare us, and to direct us into what we need to do and where we need to go. Follow the steps God gives you, take advantage of the opportunities He brings you to do things, and build relationships with other believers. Doing these things will benefit us today and help us reach our future goals.
