Matthew 18:1-5

1 At that time the disciples came to Jesus and asked, ‘Who is the greatest in the kingdom of heaven?’ 2He called a child, whom he put among them, 3and said, ‘Truly I tell you, unless you change and become like children, you will never enter the kingdom of heaven. 4Whoever becomes humble like this child is the greatest in the kingdom of heaven. 5Whoever welcomes one such child in my name welcomes me.
