Matthew 25:40-46
And the King will answer them and say, 'Truly I tell you, since you did all this for one of my least [significant] brothers, you did it for me.'
John 12:8
For you will always have poor people among you, but you will not always have me."
2 Corinthians 8:7-9
But just as you excel in everything [else]; in your faith, in your speaking; in your knowledge [Note: Possibly these refer to spiritual gifts. See I Cor. 12:8-10], in your eagerness [to serve], and in your love for us, now you people should also excel in this favorable work [i.e., of giving financial help to needy people].
1 John 3:17-21
Now whoever has [a sufficient amount of] life's possessions and [then] observes one of his [Christian] brothers who does not have enough to get by on, but does not feel sorry for him [i.e., enough to help him out], surely a love for God does not continue to live in that person's heart.
1 John 4:21
And this is the [greatest] commandment [See Matt. 2:37-38] we have received from Him: [It requires] that the person who [claims to] love God should also love his brother.
