From the Holy Bible: Gospel of Matthew, Excerpts of Chaps 18, 20-21

Then Peter came to Jesus and asked, “Lord, how many times shall I forgive my brother when he sins against me? Up to seven times?” Jesus answered,” I tell you, not seven times, but seventy-seven times.” At that time, the disciples came to Jesus and asked, “Who is the greatest in the kingdom of heaven?" He called a little child and had him stand among them. And he said, “I tell you the truth - unless you change and become like little children, you will never enter the kingdom of heaven. Therefore, whoever humbles himself like this child is the greatest in the kingdom of heaven.”
