A Glass of Fresh Water Can Do

JESUS said to His disciples in Mt 10,40-42:

Whoever accepts you, accepts me,
and whoever accepts me, accepts the one who has sent me.
Whoever accepts a prophet, because he is a prophet,
will receive the reward of a prophet.
Whoever accepts a rightous man, because he is a rightous man,
will receive the reward of a rightous man.
And whoever gives to one of these little ones a glass of fresh water,
because he is a disciple
- Amen, I say to you:
He surely will not miss his reward.
