Mark 12:41-44: And he sat down opposite the treasury, and watched the multitude putting money into the treasury. Many rich people put in large sums. And a poor widow came, and put in two copper coins, which make a penny. And he called his disciples to him, and said to them, “Truly, I say to you, this poor widow has put in more than all those who are contributing to the treasury. For they all contributed out of their abundance; but she out of her poverty has put in everything she had, her whole living."
Matthew 5:3-4: The poor in spirit are blessed, because the reign of heaven is theirs! The people who are mourning are blessed, because they will be comforted!
Romans 3:22-25: For there is no distinction; since all have sinned and fall short of the glory of God, they are justified by his grace as a gift, through the redemption which is in Christ Jesus, whom God put forward as an expiation by his blood, to be received by faith.
