Knowing God.
"You grow in knowledge of God as you know him more and more as Lord, as King. First, he is the one who controls all things. You will grow in your knowledge of God as you see more and more things as under his control: the present, the future, your own life, your sin, your salvation . . . second, you come to know God as the one who speaks with such authority that you must obey--in every area of your life: your social life, your moral life, even your intellectual life. You will grow in your knowledge of God when you come to bring every thought captive to Christ (2 Cor 10:5)" (John Frame, Salvation Belongs to the Lord, 75).
