Meet One's Maker Meaning

(idiomatic, euphemistic) To die or to pass into the afterlife.

Example: 1918, Edgar Rice Burroughs, The Land that Time Forgot, ch. 4:
  He didn't die for a half-hour after that; nor did he speak again—aloud; but just a few seconds before he went to meet his Maker, his lips moved in a faint whisper.
