"Then the righteous will answer Him, saying, 'Lord, when did we see You hungry and feed You, or thirsty and give You drink? When did we see You a stranger and take You in, or naked and clothe You? Or when did we see You sick, or in prison, and come to You?' And the King will answer and say to them, 'Assuredly, I say to you, inasmuch as you did it to one of the least of these My brethren, you did it to Me.' Matthew 25:37-40
From these words we learn at least two truths:
First, serving others is important. It is specifically important to serve the least deserving, and those Christ calls His brethren (Christians).
This text does not mean that we can earn Heaven by serving. Rather, serving validates our salvation because the redeemed serve.
Second, did you notice that the righteous didn’t think they served Christ by serving others? Why is that? I suspect there is an answer besides the obvious. True servants are so engaged in serving, they are virtually unaware that they are serving because their focus is on serving others, not on what fine servants they are.
As the redeemed, let us be servants because we are saved by God’s grace. Let us, without thought of self, serve as Christ serves us. When we do, we serve Him.
