Matthew 10:42 says this, “And whoever gives one of these little ones just a cup of cold water to drink in the name of a disciple, truly I say to you, he shall by no means lose his reward.'”
Kind of a beautiful verse. Especially when thinking about how much a cup of cold water means to those who can’t actually get clean water. What you do to the least of these you do unto Jesus.
Jesus is sending out His twelve apostles to carry His message to the people of Israel and, eventually, to the world. They will teach and do miracles in Jesus’ name and under His power and authority. They will represent Jesus so thoroughly that any who receives an apostle will be receiving both Jesus and the one who sent Him. Such people will share in the rewards to be given to the apostles.
Now Jesus describes part of what it means to receive one of His disciples, whom He calls “little ones.” The person who gives one of them a cup of cold water—because he is a disciple of Jesus—will not lose his or her reward of being included in the kingdom of heaven. The implication is that those who serve Jesus’ disciples because they believe in Jesus and want to help the mission succeed will be rewarded.
Even in Jesus’ time, people preferred to drink cold water. A cup of cold water, if available, was not expensive. Even a very poor person could help the mission of Jesus by offering His workers some cold water along the way. Wealth and status are no barrier to serving Jesus’ mission by giving assistance to His laborers.
Once again, amazing words to live by. Being kind to someone, being courteous and respectful. Giving to someone when they are in need. These are all traits of Jesus as He has taught us in this book of Matthew.
