Matthew 18
2He called a little child and had him stand among them. 3And he said: "I tell you the truth, unless you change and become like little children, you will never enter the kingdom of heaven. 4Therefore, whoever humbles himself like this child is the greatest in the kingdom of heaven.
5"And whoever welcomes a little child like this in my name welcomes me. 6But if anyone causes one of these little ones who believe in me to sin, it would be better for him to have a large millstone hung around his neck and to be drowned in the depths of the sea.
Matthew 19
14Jesus said, "Let the little children come to me, and do not hinder them, for the kingdom of heaven belongs to such as these."
Luke 18
15People were also bringing babies to Jesus to have him touch them. When the disciples saw this, they rebuked them. 16But Jesus called the children to him and said, "Let the little children come to me, and do not hinder them, for the kingdom of God belongs to such as these. 17I tell you the truth, anyone who will not receive the kingdom of God like a little child will never enter it."
All of man is sinful by nature - no one teaches us how to be self centered, but we all must be taught to share.
Romans 5
12Therefore, just as sin entered the world through one man, and death through sin, and in this way death came to all men, because all sinned—
But this does not mean that my fathers sin is my sin.
Ezekiel 18
20 The soul who sins is the one who will die. The son will not share the guilt of the father, nor will the father share the guilt of the son. The righteousness of the righteous man will be credited to him, and the wickedness of the wicked will be charged against him.
