Running after God's blessings without running after him

From D.A. Carson's A Call to Spiritual Reformation:

So much of our religion is packaged to address our felt needs - and these are almost uniformly anchored in our pursuit of our own happiness and fulfillment. God simply becomes the Great Being who, potentially at least, meets our needs and fulfills our aspirations. We think rather little of what he is like, what he expects of us, what he seeks in us. We are not captured by his holiness and love; his thoughts and words capture too little of our imagination, too little of our discourse, too few of our priorities.

In the biblical view of things, a deeper knowledge of God brings with it massive improvement in the other areas mentioned: purity, integrity, evangelistic effectiveness, better study of Scripture, improved private and corporate worship, and much more. But if we seek these things without passionately desiring a deeper knowledge of God, we are selfishly running after God's blessings without running after him. We are even worse than the man who wants his wife's services - someone to come home to, someone to cook and clean, someone to sleep with - without ever making the effort to really know and love his wife and discover what she wants and needs; we are worse than such a man, I say, because God is more than any wife, more than the best of wives: he is perfect in his love, he has made us for himself, and we are answerable to him.
