Micah 6:8 (TNIV)
He has shown all you people what is good. And what does the LORD require of you? To act justly and to love mercy and to walk humbly with your God.
Matthew 5:3-10 (TNIV)
3"Blessed are the poor in spirit, for theirs is the kingdom of heaven. 4Blessed are those who mourn, for they will be comforted. 5Blessed are the meek, for they will inherit the earth. 6Blessed are those who hunger and thirst for righteousness, for they will be filled. 7Blessed are the merciful, for they will be shown mercy. 8Blessed are the pure in heart, for they will see God. 9Blessed are the peacemakers, for they will be called children of God. 10Blessed are those who are persecuted because of righteousness, for theirs is the kingdom of heaven."
Matthew 25:34-36, 40 (TNIV)
34"Come, you who are blessed by my Father; take your inheritance, the kingdom prepared for you since the creation of the world. 35For I was hungry and you gave me something to eat, I was thirsty and you gave me something to drink, I was a stranger and you invited me in, 36needed clothes and you clothed me, I was sick and you looked after me, I was in prison and you came to visit me . . .40Truly I tell you, whatever you did for one of the least of these brothers and sisters of mine, you did for me."
I John 3: 16-18 (TNIV)
16This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for one another. 17If any one of you has material possessions and sees a brother or sister in need but has no pity on them, how can the love of God be in you? 18Dear children, let us not love with words or tongue but with actions and in truth.
Luke 12: 48 (TNIV)
From everyone who has been given much, much will be demanded; and from the one who has been entrusted with much, much more will be asked.
