John 15:13–14

Greater love has no one than this, that someone lay down his life for his friends. [14] You are my friends if you do what I command you. (ESV)

Jesus tells us there is no greater love than to die for friends. That a stranger would put their own life on the line for the sake of their nation is certainly an instance of this kind of love. In the United States, Memorial Day is a reminder to give thanks for those who did just that for American citizens everywhere. Christians should be no strangers to the concept of vicarious sacrifice of one's own life. Our example of self-sacrifice is found in none other than Jesus Himself. There is no better way to give thanks for all the sacrifices that have been made for your benefit than to praise the Savior who Himself was sacrificed for us.
