WHAT DOES IT MEAN TO BE THE FIRSTBORN?

Yahawashi is the BIG BROTHER amongst his brethren [The Elect]

Romans 8:29-31 (KJV)
29 For whom he did foreknow, he also did predestinate [to be] conformed to the image of his Son, that he might be the firstborn among many brethren. 30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified. 31 What shall we then say to these things? If God [be] for us, who [can be] against us?
