For where your treasure is, there your heart will be also. Matthew 6:21
“Jesus himself speaks of desire, of love, but also of ambition, personal striving, and self-dispossession in terms of treasure. Here treasure is not simply what we possess; it is what we love, what we cherish, what captures the human heart. Our treasure, whether God, another person, pleasure, reputation, status, wealth is that which we trust, what we count on, where we place our security. The treasure is that for which we will sacrifice all other good, sell all, making it the pre-eminent value that has no equal in our lives. All human striving is directed, whether we recognize it or not, to finding this treasure.”
