It is typically a natural thing for most of us to be an encouragement to our friends - the people we already know and trust. But, the Bible is clear that we should also be encouraging (showing hospitality to) strangers.
What does it mean to show hospitality? It means to be generous and friendly towards someone, even if you don't know them very well. It's not just about entertaining or having people over for dinner (although that is a great thing to do!) It's about showing the love of Christ through ANY act of service.
Why by hospitable? Because it's a ministry, it's what Jesus would do, and it's what He TELLS us to do. YOU may actually be the only Christian a person comes in contact with, and they could easily judge Jesus Christ by how you act toward them. With that in mind, we should always be conscious of the way we treat others. (And, you never know.... like the verse above says, you just might be helping out an angel in disguise.)
ENCOURAGEMENT CHALLENGE #4:Do something kind for someone you don’t know that shows Christian hospitality toward them. Pay for a cup of coffee or a doughnut at the coffee shop, invite a visitor at your church over for lunch after services, get to know a co-worker or a neighbor by inviting them over for an evening, volunteer at a local food pantry or soup kitchen, provide a meal or a special treat for your local fire department, police department, or Ambulance service. The list goes on. Just keep your eyes open and take the opportunity to BE JESUS to a "stranger" this week.
