I am a child of God, who is the God of the Christians and Jews. His name that we call Him by is Yahweh, so I call myself a child of Yahweh. But why am I one of His children? John 1:12 says To all who did receive [Jesus], to those who believed in His name, He gave the right to become children of God So because I believe in Jesus and have received Him, I can say: I am a child of Yahweh!
