Jesus' last word is our first word. "Tetelestai - It is finished". When He died, our life began. And because "it is finished", there is nothing that any one of us can contribute to His work on the cross to bring us any closer to salvation.
It's the word 'Yahweh' written in the original Hebrew. Yahweh was considered the most sacred name of god in the Old Testament, only the high priests knew how to even pronounce the word. It was so sacred because it's not a word to describe God, it's His actual name. And now the name of my creator is written on His creation, like a signature.
