In the end, the measure of my success as a mother will not be how well I have taught my kids or cared for them but whether I have been faithful in helping them respond to God's call on their lives.

Jesus isn't limited by the personalities of our children or by our own personalities or by our education or life skills or lack of the same. He is only limited by our trying to do his will our way, in our flesh. When he takes over, he confounds the limitations of our natural life circumstances. If we trust him, he will do whatever is necessary to accomplish his purposes in our lives, and he'll do it in his own time.
