God may lead you to assist in a ministry someplace other than your own country to travel during an emergency; however, you need a passport to do this.
I would encourage you to get one, whether you feel you need one or not. It may cost you a few dollars; I think the cost is $135 right now. It would be good for you to have one and renew it every ten years or so.
This would enable you to travel at a moment’s notice to another country to participate in crisis relief teams, share the gospel, help on a ministry project, or to visit a sick relative or friend. I would encourage you to obtain one for your good and the good of the gospel!
