Joe Thorn posts an interview with Ray Ortlund about the importance of theology. here is the middle bit.
What is the central task of the theologian?
To love the Triune God wholeheartedly, according to the Bible. Nothing complicates theology like academic detachment or worldly self-display or career ambition. Central to everything else about a theologian is a tender heart toward God, reverent toward the Scriptures.
How would you respond to those who say, “I’m not a theologian”?
I’d start out pretty nice: “Okay. God has called you to be a musician. Great.” Then I’d show my true colors: “But you cannot be the musician God wants you to be without going deeper than that. You need to think biblically about who God is, who you are, what’s gone wrong, what God has done about it through Christ, and where it’s all going. That’s theology. It changes how you see everything. So unless you want to be a shallow musician, you need to become a theologian/musician. And you can be.”
