"Vocation is 'the interplay between divine choice and human freedom,' a dynamic and exciting relationship between God and the human heart. The gift of vocation is like a divine seed that springs up in the soil of our existence, opens our hearts to God and to others, so that we can share with them the treasure we ourselves have found. This is the fundamental structure of what we mean by vocation: God calls us in love and we, in gratitude, respond to him in love." - Pope Francis
