One way of expressing this is to say that the fundamental human vocation is the call to holiness, the call to be a saint.
The saints are not just heroic people who live in history books; they are ordinary Christians who have tried to live their faith without holding anything back – to love God with their whole hearts, to love those around them without counting the cost, to work at what is worthwhile with dedication and purpose, to be people of joy and kindness and prayerfulness.
All of us are called to be saints – however weak or sinful we feel. This is not so much a command as a promise that God makes: he promises us, by giving us his Holy Spirit, that he will help us to find our true happiness in following him, and that he will give us whatever we need for the journey.
