Read Matthew 10:40-42
40 “Whoever welcomes you welcomes me; and whoever welcomes me welcomes the one who sent me. 41Whoever welcomes God’s messenger because he is God’s messenger, will share in his reward. And whoever welcomes a good man because he is good, will share in his reward. 42You can be sure that whoever gives even a drink of cold water to one of the least of these my followers because he is my follower, will certainly receive a reward.”
This passage is a part of Jesus sending his disciples out into the surrounding towns to conduct Kingdom bringing ministry. Living for Jesus results in persecution. In this context - the kindness of strangers; the gift of a glass of water - will be greatly rewarded. A smile? A word of encouragement? A loud amen? A glass of water?
Lord encourage those who share your gospel with the world. Help us to support each other.
