Though God is omnipotent He chooses not to always use His power. Though God has ultimate sovereignty He chooses not to always be controlling. Though God reigns He chooses to serve. Though God is hated He chooses to love.
Such as the Kenosis of Christ so should we pour ourselves out. Do not be one's equal or one's superior, but their servant. Look not to better yourselves in the name of self-worth, but give up prestige and position for Christ as he did for us.
Fill your child's heart with the words of Scripture and the Gospel of Jesus, so when they come of age and the calling comes, to reject Christ means they must reject everything they have known to be true.
