It is an incredible mercy to be called a servant of God, but to also be called His child is even more incredible. I love how this quote captures the differences –
“The servant with hat in hand stands at a respectful distance awaiting the orders of his master. The child of God…rushes into the presence of his father, leaps into his lap, and nestles in his bosom.”
