…thinking is not at the expense of feeling or delighting or loving. Both are essential to being human, and both are essential to glorifying God. And, while it is true that mind and heart are mutually enlivening, it is also clear that the mind is mainly the servant of the heart. That is, the mind serves to know the truth that fuels the fires of the heart. The apex of glorifying God is enjoying him with the heart. But this is an empty emotionalism where that joy is not awakened and sustained by true views of God for who he really is. That is mainly what the mind is for.
