Being known by God is a critical concept in the Bible. It is, however, neglected in exegesis and theology. This article wants to revive interest in the theme by reflecting on its definition and considering its pastoral function in the Bible. Being known by God is roughly equivalent to three related ideas: belonging to God, being loved or chosen by God, and being a child of God. Being known by God promotes humility and supplies comfort and security. Its implications for anthropology and ethics are also briefly considered.
