Perhaps it is an Easter lesson:
Matthew 25:34-40
English Standard Version (ESV)
34 Then the King will say to those on his right, `Come, you who are blessed by my Father, inherit the kingdom prepared for you from the foundation of the world. 35 For I was hungry and you gave me food, I was thirsty and you gave me drink, I was a stranger and you welcomed me, 36 I was naked and you clothed me, I was sick and you visited me, I was in prison and you came to me.' 37 Then the righteous will answer him, saying, `Lord, when did we see you hungry and feed you, or thirsty and give you drink? 38 And when did we see you a stranger and welcome you, or naked and clothe you? 39 And when did we see you sick or in prison and visit you?' 40 And the King will answer them, `Truly, I say to you, as you did it to one of the least of these my brothers,[a] you did it to me.'
