Psa. 27:4 ¶ One thing have I asked of the LORD,
that will I seek after:
that I may dwell in the house of the LORD
all the days of my life,
to gaze upon the beauty of the LORD
and to inquire in his temple.
Following your heart can be quite confusing. Sometimes our heart can be quite deceiving, especially to ourselves. Having our heart changed is at the very center of what the Christian life is all about. How can we change our heart? Actually it is quite simple and hard at the same time. It is simple because we are to follow what we love. It is hard for the same reasons, we often love the wrong things. That is where the power of the gospel comes in. Our heart is changed, the very fabric of what we love, by the power of God’s love. He loves us into this new life of obedience. Here is how Dane Ortlund explains it in his book about the preaching of Jonathan Edwards.
“The heart of obedience is not summoning the will to do what it loathes. Rather, obedience is fruit- it is the outward manifestation of inward health. We naturally blossom because we are planted in the soil of the gospel with the sun of divine grace shining upon us. Obedience does not come out of a new raw power to now do what we don’t want to do; obedience comes because we now delight to do what we hated before. To obey is thus not to mechanically force our behavior into line with God’s moral law so much as it is living out a new delight in God. Burgeoning bank accounts, lavish vacations, orgasmic pleasure, celebrity-like fame; such things have lost their luster. We have seen real beauty.”
Edwards also spoke about the role beauty plays in the changing of our heart.
“Holiness is a most beautiful and lovely thing. We drink in strange notions of holiness from our childhood, as if it were a melancholy, [morose, sour,] and unpleasant thing; but there is nothing in it but what is sweet and ravishingly lovely. ‘Tis the highest beauty and amiableness, vastly above all other beauties; ’tis a divine beauty, makes the soul heavenly and far purer than anything here on earth (this world is like mire and filth and defilement, to that soul which is sanctified); ’tis of a sweet, pleasant, charming, lovely, amiable, delightful, serene, calm, and still nature;”
So yeah, it does pay to follow our heart after our heart has tasted true beauty for itself. Once that happens, like David, your life will become fixated on the beauty of God.
