'My Children' in the Bible

His disciples were startled at this statement. But Jesus again said to them as He continued the topic, "My children, how hard it is to get into the kingdom of God!

And suppose he answers from inside, 'Stop bothering me; the door is now locked, and my children are packed about me in bed; I cannot get up and give you any.'

To pay me back, I tell you, my children, you too must stretch your hearts with love for me.

I have no greater spiritual blessing than this, to hear that my children are living by the truth.
