Martyn Lloyd-Jones reminds us that no matter how much we know or study, eternally it does not matter if we aren’t investing that knowledge in good, holy, pleasing, acceptable, worthy things, and eternal things. He writes,
You can be so interested in great theological and intellectual and philosophical problems that you tend to forget that you are going to die.
So, when we learn doctrines and other great, deep truths of God’s word, may we apply them to our lives with the Lord and others in a way that brings God the most glory, others the most edification, and us the most satisfaction. Many times we can learn and learn and learn and have a head-full of book knowledge, yet not a speck of ministerial or personal experience with the particular doctrine. Let us drink of the deep rivers of God’s truth and live in a way that shows Jesus is our Treasure and not the knowledge he gives.
