One of the Advent texts is taken from Isaiah 40: 3-10, and it is about clearing the way for the Lord. As is well known, the word Advent means "the coming of the Lord". And this is also what the various Advent texts focus on. The name Lord, YHVH, is used for both God and Christ Jesus (Romans 10: 9; Phil. 2:11). And besides, both are called, both God and Christ, for I AM (ego eimi, Exodus 3: 14-14) . So they are both God and the Lord.
