I've read that when Edward VI, the king of England in the 16th century, attended a worship service, he stood while the Word of God was read. He took notes during this time and later studied them with great care. Through the week he earnestly tried to apply them to his life.
That's the kind of serious-minded response to truth the apostle James calls for in today's Scripture reading. A single revealed fact cherished in the heart and acted upon is more vital to our growth than a head filled with lofty ideas about God.
