And there was great joy in that city.
Now an angel of the Lord spoke to Philip, saying, "Arise and go toward the south along the road which goes down from Jerusalem to Gaza." This is desert."
Acts 8:5, 8, 26 (NKJV)
Usually when we are traveling to some place, we look for the fastest route, which is usually the shortest route. But often there are other routes that can be taken to get to the same destination. However, sometimes you may not want to take the more direct route, because you want, or need, to see or do something along the way to your destination. The shortest route may not always be the best route to get you to the place you are going to.
Philip went to the city of Samaria and preached Christ to the people there; his time in Samaria was successful, and there was great joy in the city. But the next thing we see is that Philip is instructed to take the road the goes from Jerusalem to Gaza, which is a desert area. If we would look at this like many people do, we might think that Philip was doing something wrong, because he goes from a meeting that touched an entire city into the desert where he meets just one man.
But, while the route that Philip took may seem strange to us, we can't look at this, or any direction we or others have from God, based on what we see and what we know. There are times that God will lead us in a direction that does not seem to make sense to us, but we must trust God and His leading, because He will always lead us in the best way to go. To have successful direction, we must follow God's plan to go where He leads us, no matter how it may look to ourselves or to others.
