Opening boxes...

To quote Tim Challies:

A third way we can put God in a box is by making theology an end in itself. We are all prone to this error, but perhaps Reformed Christians more than others. In our flawed, limited understanding of God, we can make an idol of theology. Rather than studying God with a view to making theology a practical outpouring of the wonder of who He is, we succumb to theology-ology, or "the study of the study of God." This lazy study leads only to puffed-up knowledge with little practical application. An unbeliever can study the study of God as easily as a Christian, for it does not depend on the Spirit to apply the words to our lives.

Jesus warned "Not everyone who says to me, 'Lord, Lord,' will enter the kingdom of heaven, but the one who does the will of my Father who is in heaven. On that day many will say to me, 'Lord, Lord, did we not prophesy in your name, and cast out demons in your name, and do many mighty works in your name?' And then will I declare to them, 'I never knew you; depart from me, you workers of lawlessness.' (Matthew 7:21-23). In the last days there will be many who have accumulated vast knowledge of God, but who have never truly known Him. They will know about God without ever knowing Him. They will be cast into the lake of fire despite their great knowledge of the Bible and biblical theology.
