The single greatest priority of my life is to make sure that God is the focus of my affection, the focus of my thinking and ONE CONSUMING PASSION OF MY SOUL.
Anything less than that is sin, and not some simple little insignificant sin. It is the GREATEST SIN of all. If God is not the focus of my affection, and the focus of my thinking and the ONE CONSUMING PASSION OF MY SOUL, then something else occupies that place in my life. Something has taken the place of God in my heart.
