Question: How could You have just come into existence?
God's answer:
The name YHWH (Yahweh)
The capital letter I
A heart with the word AM
Meaning: “The tetragrammaton (meaning "consisting of) four letters") is the Hebrew theonym הוהי, commonly transliterated into Latin letters as YHWH.”1.
YHWH is the name of God revealed to Moses. The meaning of God’s name YHWH is said to be "He causes to be", "He Creates", “I am all that was, is and will be” or “I am that I am”. According to God, YHWH means: “My Identity”, “I AM the I AM”.
