God has called us to be like children, but what does that mean? If you think back to your childhood, you obeyed your parents and listened to what they said. You did what they told you. In our relationship with God, He calls us to be like that with Him. When He tells us to do something we ought to obey that command. We ought to act in child like faith, have faith that God will come through, not doubting, just faith.
Let us return to the heart of the Father where He called us to live like children in His kingdom.
