CCC 211

The divine name, "I Am" or "He Is", expresses God's faithfulness: despite the faithlessness of men's sin and the punishment it deserves, he keeps "steadfast love for thousands".²¹ Ex 34:7 By going so far as to give up his own Son for us, God reveals that he is "rich in mercy".²² Eph 2:4 By giving his life to free us from sin, Jesus reveals that he himself bears the divine name: "When you have lifted up the Son of man, then you will realize that "I AM"."²³ Jn 8:28 (Greek).
