who have borne witness of your love before the church. If you send them forward on their journey in a manner worthy of God, you will do well,
because they went forth for His name's sake, taking nothing from the Gentiles."
3 John 1:5-7 (NKJV)
When traveling through an airport, you can find all kinds of places to buy things that you might need when you travel. You could find something that you had forgotten to pack, or something that would be helpful for you on your trip. It seems that in airports today, you can find almost anything you might need to help you on your journey. All of these places can help you with what you might need along the way, even though none of these places are your actual destination.
There are many ways we can serve God, and one way is by helping others in the things that God has called them to do. In 3 John, the Apostle John wrote to believers about how good it is for believers to help others along the way as they are serving God. God has a plan and purpose for each and every person, and while we can't fulfill the will of God for someone else, we can do things that will help those other people move forward on their journey as they fulfill the will of God in their lives.
We may not be a pastor, but there are things we can do to help our pastor. We may not be a missionary, but there are things we can do to help those serving in other nations. There are many things we may not be specifically called to do ourselves, but there are ways to help others, by praying for them, finding some way to assist them in what they are doing, and even just with some encouraging words. We all need to do what we can to find ways to help others along the way as they serve God.
