"Get the truth and never sell it;
also get wisdom, discipline, and good judgment."
What could be clearer direction than these words? Get truth. Prize it so much that you'd never sell it for anything, because nothing else is worth it. Also, prize wisdom highly that has been gleaned from the Holy Spirit showing you how to apply God's Word to your life. Then there's discipline—the ability to sacrifice short-term gain for long-term reward—and finally good judgment (common sense). Prize these and prosper!
