The King of rock and roll and one the greatest medieval preachers. One wouldn’t think they have much overlap in fundamental messages but when it comes to the nature of love, you’d be wrong.
To love is to desire another. To love rightly is to desire not just what another can give to you. It is not to love merely how they make you feel. It is not to seek self-gratification in another.
It is to love them for them. No more appropriate is this than when we speak of loving God, our first and most important duty, both Old and New Covenant. Can we love God not only for what He gives to us, though his gifts are many? Can we love God not for how he enriches us or how he makes us feel? Can we love God for God?
